       "New features:
      
         - Cr50 I2C TPM driver
      
         - sysfs exports of PCR registers in TPM 2.0 chips
      
        Bug fixes:
      
         - bug fixes for tpm_tis driver, which had a racy wait for hardware
           state change to be ready to send a command to the TPM chip. The bug
           has existed already since 2006, but has only made itself known in
           recent past. This is the same as the "last time" :-)
      
         - Otherwise there's bunch of fixes for not as alarming regressions. I
           think the list is about the same as last time, except I added fixes
           for some disjoint bugs in trusted keys that I found some time ago"

      Pull selinux updates from Paul Moore:
       "We've got a good handful of patches for SELinux this time around; with
        everything passing the selinux-testsuite and applying cleanly to your
        tree as of a few minutes ago. The highlights are:
      
         - Add support for labeling anonymous inodes, and extend this new
           support to userfaultfd.
      
         - Fallback to SELinux genfs file labeling if the filesystem does not
           have xattr support. This is useful for virtiofs which can vary in
           its xattr support depending on the backing filesystem.
      
         - Classify and handle MPTCP the same as TCP in SELinux.
      
         - Ensure consistent behavior between inode_getxattr and
           inode_listsecurity when the SELinux policy is not loaded. This
           fixes a known problem with overlayfs.
      
         - A couple of patches to prune some unused variables from the SELinux
           code, mark private variables as static, and mark other variables as
           __ro_after_init or __read_mostly"

      Pull KVM updates from Paolo Bonzini:
       "x86:
      
         - Support for userspace to emulate Xen hypercalls
      
         - Raise the maximum number of user memslots
      
         - Scalability improvements for the new MMU.
      
           Instead of the complex "fast page fault" logic that is used in
           mmu.c, tdp_mmu.c uses an rwlock so that page faults are concurrent,
           but the code that can run against page faults is limited. Right now
           only page faults take the lock for reading; in the future this will
           be extended to some cases of page table destruction. I hope to
           switch the default MMU around 5.12-rc3 (some testing was delayed
           due to Chinese New Year).
      
         - Cleanups for MAXPHYADDR checks
      
         - Use static calls for vendor-specific callbacks
      
         - On AMD, use VMLOAD/VMSAVE to save and restore host state
      
         - Stop using deprecated jump label APIs
      
         - Workaround for AMD erratum that made nested virtualization
           unreliable
      
         - Support for LBR emulation in the guest
      
         - Support for communicating bus lock vmexits to userspace

         - Cleanups for concurrent translation faults hitting the same page
      
         - Support for the standard TRNG hypervisor call
      
         - A bunch of small PMU/Debug fixes
      
         - Simplification of the early init hypercall handling
      
        Non-KVM changes (with acks):
      
         - Detection of contended rwlocks (implemented only for qrwlocks,
           because KVM only needs it for x86)

      Pull scheduler updates from Ingo Molnar:
       "Core scheduler updates:
      
         - Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the
           preempt=none/voluntary/full boot options (default: full), to allow
           distros to build a PREEMPT kernel but fall back to close to
           PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via
           a boot time selection.
      
           There's also the /debug/sched_debug switch to do this runtime.
      
           This feature is implemented via runtime patching (a new variant of
           static calls).
      
           The scope of the runtime patching can be best reviewed by looking
           at the sched_dynamic_update() function in kernel/sched/core.c.
      
           ( Note that the dynamic none/voluntary mode isn't 100% identical,
             for example preempt-RCU is available in all cases, plus the
             preempt count is maintained in all models, which has runtime
             overhead even with the code patching. )
      
           The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast
           majority of distributions, are supposed to be unaffected.
      
         - Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that
           was found via rcutorture triggering a hang. The bug is that
           rcu_idle_enter() may wake up a NOCB kthread, but this happens after
           the last generic need_resched() check. Some cpuidle drivers fix it
           by chance but many others don't.
      
           In true 2020 fashion the original bug fix has grown into a 5-patch
           scheduler/RCU fix series plus another 16 RCU patches to address the
           underlying issue of missed preemption events. These are the initial
           fixes that should fix current incarnations of the bug.
      
         - Clean up rbtree usage in the scheduler, by providing & using the
           following consistent set of rbtree APIs:
      
             partial-order; less() based:
               - rb_add(): add a new entry to the rbtree
               - rb_add_cached(): like rb_add(), but for a rb_root_cached
      
             total-order; cmp() based:
               - rb_find(): find an entry in an rbtree
               - rb_find_add(): find an entry, and add if not found
      
               - rb_find_first(): find the first (leftmost) matching entry
               - rb_next_match(): continue from rb_find_first()
               - rb_for_each(): iterate a sub-tree using the previous two
      
         - Improve the SMP/NUMA load-balancer: scan for an idle sibling in a
           single pass. This is a 4-commit series where each commit improves
           one aspect of the idle sibling scan logic.
      
         - Improve the cpufreq cooling driver by getting the effective CPU
           utilization metrics from the scheduler
      
         - Improve the fair scheduler's active load-balancing logic by
           reducing the number of active LB attempts & lengthen the
           load-balancing interval. This improves stress-ng mmapfork
           performance.
      
         - Fix CFS's estimated utilization (util_est) calculation bug that can
           result in too high utilization values
      
        Misc updates & fixes:
      
         - Fix the HRTICK reprogramming & optimization feature
      
         - Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
      
         - Reduce dl_add_task_root_domain() overhead
      
         - Fix uprobes refcount bug
      
         - Process pending softirqs in flush_smp_call_function_from_idle()
      
         - Clean up task priority related defines, remove *USER_*PRIO and
           USER_PRIO()
      
         - Simplify the sched_init_numa() deduplication sort
      
         - Documentation updates
      
         - Fix EAS bug in update_misfit_status(), which degraded the quality

      Pull xfs updates from Darrick Wong:
       "There's a lot going on this time, which seems about right for this
        drama-filled year.
      
        Community developers added some code to speed up freezing when
        read-only workloads are still running, refactored the logging code,
        added checks to prevent file extent counter overflow, reduced iolock
        cycling to speed up fsync and gc scans, and started the slow march
        towards supporting filesystem shrinking.
      
        There's a huge refactoring of the internal speculative preallocation
        garbage collection code which fixes a bunch of bugs, makes the gc
        scheduling per-AG and hence multithreaded, and standardizes the retry
        logic when we try to reserve space or quota, can't, and want to
        trigger a gc scan. We also enable multithreaded quotacheck to reduce
        mount times further. This is also preparation for background file gc,
        which may or may not land for 5.13.
      
        We also fixed some deadlocks in the rename code, fixed a quota
        accounting leak when FSSETXATTR fails, restored the behavior that
        write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
        where sgid directory inheritance wasn't quite working properly, and
        fixed a bug where symlinks weren't working properly in ecryptfs. We
        also now advertise the inode btree counters feature that was
        introduced two cycles ago.
      
        Summary:
      
         - Fix an ABBA deadlock when renaming files on overlayfs.
      
         - Make sure that we can't overflow the inode extent counters when
           adding to or removing extents from a file.
      
         - Make directory sgid inheritance work the same way as all the other
           filesystems.
      
         - Don't drain the buffer cache on freeze and ro remount, which should
           reduce the amount of time if read-only workloads are continuing
           during the freeze.
      
         - Fix a bug where symlink size isn't reported to the vfs in ecryptfs.
      
         - Disentangle log cleaning from log covering. This refactoring sets
           us up for future changes to the log, though for now it simply means
           that we can use covering for freezes, and cleaning becomes
           something we only do at unmount.
      
         - Speed up file fsyncs by reducing iolock cycling.
      
         - Fix delalloc blocks leaking when changing the project id fails
           because of input validation errors in FSSETXATTR.
      
         - Fix oversized quota reservation when converting unwritten extents
           during a DAX write.
      
         - Create a transaction allocation helper function to standardize the
           idiom of allocating a transaction, reserving blocks, locking
           inodes, and reserving quota. Replace all the open-coded logic for
           file creation, file ownership changes, and file modifications to
           use them.
      
         - Actually shut down the fs if the incore quota reservations get
           corrupted.
      
         - Fix background block garbage collection scans to not block and to
           actually clean out CoW staging extents properly.
      
         - Run block gc scans when we run low on project quota.
      
         - Use the standardized transaction allocation helpers to make it so
           that ENOSPC and EDQUOT errors during reservation will back out,
           invoke the block gc scanner, and try again. This is preparation for
           introducing background inode garbage collection in the next cycle.
      
         - Combine speculative post-EOF block garbage collection with
           speculative copy on write block garbage collection.
      
         - Enable multithreaded quotacheck.
      
         - Allow sysadmins to tweak the CPU affinities and maximum concurrency
           levels of quotacheck and background blockgc worker pools.
      
         - Expose the inode btree counter feature in the fs geometry ioctl.
      
         - Cleanups of the growfs code in preparation for starting work on
           filesystem shrinking.
      
         - Fix all the bloody gcc warnings that the maintainer knows about. :P
      
         - Fix a RST syntax error.
      
         - Don't trigger bmbt corruption assertions after the fs shuts down.
      
         - Restore behavior of forcing SIGBUS on a shut down filesystem when
           someone triggers a mmap write fault (or really, any buffered
           write)"

       "The big change in this cycle is some new code to make it possible for

       "This contains a somewhat important but rarely reproduced fix reported
        month ago for platforms which have weak memory model (e.g. arm64).
      
        The root cause is that test_bit/set_bit atomic operations are actually
        implemented in relaxed forms, and uninitialized fields governed by an
        atomic bit could be observed in advance due to memory reordering thus
        memory barrier pairs should be used.
      
        There is also a trivial fix of crafted blkszbits generated by
        syzkaller.
      
        Summary:
      
         - fix shift-out-of-bounds of crafted blkszbits generated by syzkaller
      
         - ensure initialized fields can only be observed after bit is set"

      Pull f2fs updates from Jaegeuk Kim:
       "We've added two major features: 1) compression level and 2)
        checkpoint_merge, in this round.
      
        Compression level expands 'compress_algorithm' mount option to accept
        parameter as format of <algorithm>:<level>, by this way, it gives a
        way to allow user to do more specified config on lz4 and zstd
        compression level, then f2fs compression can provide higher compress
        ratio.
      
        checkpoint_merge creates a kernel daemon and makes it to merge
        concurrent checkpoint requests as much as possible to eliminate
        redundant checkpoint issues. Plus, we can eliminate the sluggish issue
        caused by slow checkpoint operation when the checkpoint is done in a
        process context in a cgroup having low i/o budget and cpu shares.
      
        Enhancements:
         - add compress level for lz4 and zstd in mount option
         - checkpoint_merge mount option
         - deprecate f2fs_trace_io
      
        Bug fixes:
         - flush data when enabling checkpoint back
         - handle corner cases of mount options
         - missing ACL update and lock for I_LINKABLE flag
         - attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
         - fix potential deadlock in compression flow
         - fix wrong submit_io condition
      
        As usual, we've cleaned up many code flows and fixed minor bugs"
