      1 warning generated.
      
      The return value of debugfs_create_file does not need to be checked [1]
      and the function returns void so get rid of the ternary operator, it is
      unnecessary.

      usbnet: sanity checking of packet sizes and device mtu · 280ceaed
      Oliver Neukum authored
      After a reset packet sizes and device mtu can change and need
      to be reevaluated to calculate queue sizes.
      Malicious devices can set this to zero and we divide by it.
      Introduce sanity checking.

       "For this cycle we have the usual pile of cleanups and bug fixes, some
        performance improvements for online metadata scrubbing, massive
        speedups in the directory entry creation code, some performance
        improvement in the file ACL lookup code, a fix for a logging stall
        during mount, and fixes for concurrency problems.
      
        It has survived a couple of weeks of xfstests runs and merges cleanly.
      
        Summary:
      
         - Remove KM_SLEEP/KM_NOSLEEP.
      
         - Ensure that memory buffers for IO are properly sector-aligned to
           avoid problems that the block layer doesn't check.
      
         - Make the bmap scrubber more efficient in its record checking.
      
         - Don't crash xfs_db when superblock inode geometry is corrupt.
      
         - Fix btree key helper functions.
      
         - Remove unneeded error returns for things that can't fail.
      
         - Fix buffer logging bugs in repair.
      
         - Clean up iterator return values.
      
         - Speed up directory entry creation.
      
         - Enable allocation of xattr value memory buffer during lookup.
      
         - Fix readahead racing with truncate/punch hole.
      
         - Other minor cleanups.
      
         - Fix one AGI/AGF deadlock with RENAME_WHITEOUT.
      
         - More BUG -> WARN whackamole.
      
         - Fix various problems with the log failing to advance under certain
           circumstances, which results in stalls during mount"

       "This continues with work on code refactoring, sanity checks and space
        handling. There are some less user visible changes, nothing that would
        particularly stand out.
      
        User visible changes:
         - tree checker, more sanity checks of:
             - ROOT_ITEM (key, size, generation, level, alignment, flags)
             - EXTENT_ITEM and METADATA_ITEM checks (key, size, offset,
               alignment, refs)
             - tree block reference items
             - EXTENT_DATA_REF (key, hash, offset)
      
         - deprecate flag BTRFS_SUBVOL_CREATE_ASYNC for subvolume creation
           ioctl, scheduled removal in 5.7
      
         - delete stale and unused UAPI definitions
           BTRFS_DEV_REPLACE_ITEM_STATE_*
      
         - improved export of debugging information available via existing

           orphan entries
      
         - remove unreliable space checks before relocation starts
      
        Core:
         - space handling:
             - improved ticket reservations and other high level logic in
               order to remove special cases
             - factor flushing infrastructure and use it for different

             - reduce metadata reservation when only updating inodes
             - reduce global block reserve minimum size (affects small
               filesystems)
             - improved overcommit logic wrt global block reserve
      
         - tests:
             - fix memory leaks in extent IO tree
             - catch all TRIM range
      
        Fixes:
         - fix ENOSPC errors, leading to transaction aborts, when cloning

      Pull fs-verity support from Eric Biggers:
       "fs-verity is a filesystem feature that provides Merkle tree based
        hashing (similar to dm-verity) for individual readonly files, mainly
        for the purpose of efficient authenticity verification.
      
        This pull request includes:
      
         (a) The fs/verity/ support layer and documentation.
      
         (b) fs-verity support for ext4 and f2fs.
      
        Compared to the original fs-verity patchset from last year, the UAPI
        to enable fs-verity on a file has been greatly simplified. Lots of
        other things were cleaned up too.
      
        fs-verity is planned to be used by two different projects on Android;
        most of the userspace code is in place already. Another userspace tool
        ("fsverity-utils"), and xfstests, are also available. e2fsprogs and
        f2fs-tools already have fs-verity support. Other people have shown
        interest in using fs-verity too.
      
        I've tested this on ext4 and f2fs with xfstests, both the existing
        tests and the new fs-verity tests. This has also been in linux-next
        since July 30 with no reported issues except a couple minor ones I
        found myself and folded in fixes for.
      
        Ted and I will be co-maintaining fs-verity"

      Pull fscrypt updates from Eric Biggers:
       "This is a large update to fs/crypto/ which includes:
      
         - Add ioctls that add/remove encryption keys to/from a
           filesystem-level keyring.
      
           These fix user-reported issues where e.g. an encrypted home
           directory can break NetworkManager, sshd, Docker, etc. because they
           don't get access to the needed keyring. These ioctls also provide a
           way to lock encrypted directories that doesn't use the
           vm.drop_caches sysctl, so is faster, more reliable, and doesn't
           always need root.
      
         - Add a new encryption policy version ("v2") which switches to a more
           standard, secure, and flexible key derivation function, and starts
           verifying that the correct key was supplied before using it.
      
           The key derivation improvement is needed for its own sake as well
           as for ongoing feature work for which the current way is too
           inflexible.
      
        Work is in progress to update both Android and the 'fscrypt' userspace
        tool to use both these features. (Working patches are available and
        just need to be reviewed+merged.) Chrome OS will likely use them too.
      
        This has also been tested on ext4, f2fs, and ubifs with xfstests --
        both the existing encryption tests, and the new tests for this. This
        has also been in linux-next since Aug 16 with no reported issues. I'm
        also using an fscrypt v2-encrypted home directory on my personal

        Two major chunks of code are moving out of the tree and into the

        are no devices that actually use this protocol anymore, and what we

        left many many years ago. So move it to staging where it will be
        removed in a few releases if no one screams.
      
        Other than that, lots of little things. The usual gadget and xhci and
        usb serial driver updates, along with a bunch of sysfs file cleanups

      Pull driver core updates from Greg Kroah-Hartman:
       "Here is the big driver core update for 5.4-rc1.
      
        There was a bit of a churn in here, with a number of core and OF
        platform patches being added to the tree, and then after much
        discussion and review and a day-long in-person meeting, they were
        decided to be reverted and a new set of patches is currently being
        reviewed on the mailing list.
      
        Other than that churn, there are two "persistent" branches in here
        that other trees will be pulling in as well during the merge window.
        One branch to add support for drivers to have the driver core
        automatically add sysfs attribute files when a driver is bound to a
        device so that the driver doesn't have to manually do it (and then
        clean it up, as it always gets it wrong).
      
        There's another branch in here for generic lookup helpers for the
        driver core that lots of busses are starting to use. That's the
        majority of the non-driver-core changes in this patch series.
      
        There's also some on-going debugfs file creation cleanup that has been
        slowly happening over the past few releases, with the goal to
        hopefully get that done sometime next year.
      
        All of these have been in linux-next for a while now with no reported
        issues"
      
      [ Note that the above-mentioned generic lookup helpers branch was
        already brought in by the LED merge (commit 4feaab05) that had
        shared it.
      
        Also note that that common branch introduced an i2c bug due to a bad
        conversion, which got fixed here. - Linus ]
