Pull xfs ioctl housecleaning from Darrick Wong: "This is the first of a series of small pull requests that perform some long overdue housecleaning of XFS ioctls. This first pull request removes the FSSETDM ioctl, which was used to set DMAPI event attributes on XFS files. The DMAPI support has never been merged upstream and the implementation of FSSETDM itself was removed two years ago, so let's withdraw it completely. - Withdraw the ioctl definition for the FSSETDM ioctl" * tag 'xfs-5.17-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: remove the XFS_IOC_FSSETDM definitions

It solves some long-standing issues with using different auth entities and/or mounting different CephFS filesystems from the same cluster, remounting and also misleading /proc/mounts contents. The existing syntax of course remains to be maintained.

Until recent versions of GCC and Clang, it was not possible to disable KCOV instrumentation via a function attribute. The relevant function attribute was introduced in 540540d0 ("kcov: add __no_sanitize_coverage to fix noinstr for all architectures"). x86 was the first architecture to want a working noinstr, and at the time no compiler support for the attribute existed yet. Therefore, commit 0f1441b4 ("objtool: Fix noinstr vs KCOV") introduced the ability to NOP __sanitizer_cov_*() calls in .noinstr.text. However, this doesn't work for other architectures like arm64 and s390 that want a working noinstr per ARCH_WANTS_NO_INSTR. At the time of 0f1441b4, we didn't yet have ARCH_WANTS_NO_INSTR, but now we can move the Kconfig dependency checks to the generic KCOV option. KCOV will be available if: - architecture does not care about noinstr, OR - we have objtool support (like on x86), OR - GCC is 12.0 or newer, OR - Clang is 13.0 or newer.

Commit b05fbcc3 ("btrfs: disable build on platforms having page size 256K") disabled btrfs for configurations that used a 256kB page size. However, it did not fully solve the problem because CONFIG_TEST_KMOD selects CONFIG_BTRFS, which does not account for the dependency. This results in a Kconfig warning and the failed BUILD_BUG_ON error returning.

Patch series "Fix CONFIG_TEST_KMOD with 256kB page size". The kernel test robot reported a build error [1] from a failed assertion in fs/btrfs/inode.c with a hexagon randconfig that includes CONFIG_PAGE_SIZE_256KB. This error is the same one that was addressed by commit b05fbcc3 ("btrfs: disable build on platforms having page size 256K") but CONFIG_TEST_KMOD selects CONFIG_BTRFS without having the "page size less than 256kB dependency", which results in the error reappearing. The first patch introduces CONFIG_PAGE_SIZE_LESS_THAN_256KB by splitting it off from CONFIG_PAGE_SIZE_LESS_THAN_64KB, which was introduced in commit 1f0e290c ("arch: Add generic Kconfig option indicating page size smaller than 64k") for a similar reason in 5.16-rc3. The second patch uses that configuration option for CONFIG_BTRFS to reduce duplication. The third patch resolves the build error by adding CONFIG_PAGE_SIZE_LESS_THAN_256KB as a dependency to CONFIG_TEST_KMOD so that CONFIG_BTRFS does not get enabled under that invalid configuration. [1]: https://lore.kernel.org/r/202111270255.UYOoN5VN-lkp@intel.com/ This patch (of 3): btrfs requires a page size smaller than 256kB. To use that dependency in other places, introduce CONFIG_PAGE_SIZE_LESS_THAN_256KB and reuse that dependency in CONFIG_PAGE_SIZE_LESS_THAN_64KB.

Some general debugging features like kmemleak, KASAN, lockdep, UBSAN etc help fix many viruses like a microscope. On the other hand, those features are scatter around and mixed up with more situational debugging options making them difficult to consume properly. This cold help amplify the general debugging/testing efforts and help establish sensitive default values for those options across the broad. This could also help different distros to collaborate on maintaining debug-flavored kernels. The config is based on years' experiences running daily CI inside the largest enterprise Linux distro company to seek regressions on linux-next builds on different bare-metal and virtual platforms. It can be used for example, $ make ARCH=arm64 defconfig debug.config Since KASAN and KCSAN can't be enabled together, we will need to create a separate one for KCSAN later as well.

Currently delayacct accounts swapin delay only for swapping that cause blkio. If we use zram for swapping, tools/accounting/getdelays can't get any SWAP delay. It's useful to get zram swapin delay information, for example to adjust compress algorithm or /proc/sys/vm/swappiness. Reference to PSI, it accounts any kind of swapping by doing its work in swap_readpage(), no matter whether swapping causes blkio. Let delayacct do the similar work.

The oops id has been added as part of the end of trace marker for the kerneloops.org project. The id is used to automatically identify duplicate submissions of the same report. Identical looking reports with different a id can be considered as the same oops occurred again. The early initialisation of the oops_id can create a warning if the random core is not yet fully initialized. On PREEMPT_RT it is problematic if the id is initialized on demand from non preemptible context. The kernel oops project is not available since 2017. Remove the oops_id and use 0 in the output in case parser rely on it. Link: https://bugs.debian.org/953172 Link: https://lkml.kernel.org/r/Ybdi16aP2NEugWHq@linutronix.deSigned-off-by:

congestion_wait() in this context is just a sleep - block devices do not support congestion signalling any more. The goal for this wait, which was introduced in commit ae78bf9c ("[PATCH] add -o flush for fat") is to wait for any recently written data to get to storage. We currently have no direct mechanism to do this, so a simple wait that behaves identically to the current congestion_wait() is the best we can do. This is a step towards removing congestion_wait() Link: https://lkml.kernel.org/r/163936544519.22433.13400436295732112065@noble.neil.brown.nameSigned-off-by:

Extend commit ce81bb25 ("fs/binfmt_elf: use PT_LOAD p_align values for suitable start address") which fixed PIE binaries built with -Wl,-z,max-page-size=0x200000, to cover static PIE binaries. This fixes: https://bugzilla.kernel.org/show_bug.cgi?id=215275 Tested by verifying static PIE binaries with -Wl,-z,max-page-size=0x200000 loading.

One exceptions to the COMMIT_LOG_LONG_LINE rule is a file path followed by ':'. That is typically some sort diagnostic message from a compiler or a build tool, in which case we don't want to wrap the lines but keep the message unmodified. The regular expression used to match this pattern currently doesn't accept absolute paths or + characters. This can result in false positives as in the following (out-of-tree) example: ... /home/jerome/work/optee_repo_qemu/build/../toolchains/aarch32/bin/arm-linux-gnueabihf-ld.bfd: /home/jerome/work/toolchains-gcc10.2/aarch32/bin/../lib/gcc/arm-none-linux-gnueabihf/10.2.1/../../../../arm-none-linux-gnueabihf/lib/libstdc++.a(eh_alloc.o): in function `__cxa_allocate_exception': /tmp/dgboter/bbs/build03--cen7x86_64/buildbot/cen7x86_64--arm-none-linux-gnueabihf/build/src/gcc/libstdc++-v3/libsupc++/eh_alloc.cc:284: undefined reference to `malloc' ... Update the regular expression to match the above paths. Link: https://lkml.kernel.org/r/20210923143842.2837983-1-jerome@forissier.orgSigned-off-by:

Use KUnit framework to make tests more easily integrable with CIs. Even though these tests are not yet properly written as unit tests this change should help in debugging. Also remove kernel messages (i.e. through pr_info) as KUnit handles all debugging output and let it handle module init and exit details.

Split up test_hash_init so that it calls each test more explicitly insofar it is possible without rewriting the entire file. This aims at improving readability. Split tests performed on string_or as they don't interfere with those performed in hash_or. Also separate pr_info calls about skipped tests as they're not part of the tests themselves, but only warn about (un)defined arch-specific hash functions.
