Subject: [ANNOUNCE] The Linux Test Project has been released for MAY 2022 

Good news everyone,

the Linux Test Project test suite stable release for *May 2022* has been
released.

Since the last release 298 patches by 25 authors were merged.

Patch review is what most of the projects struggle with and LTP is no
different. If you can spare some effort helping with the patch review is more
than welcomed.

  - futex_waitv01 error tests
  - futex_waitv02 basic functional test with private memory
  - futex_waitv03 basic functional test with shared memory
  - inotify11: test opening files after receiving IN_DELETE
               regression test for a37d9a17f099 (fsnotify: invalidate dcache before IN_DELETE event)
  - statx09 test for STATX_ATTR_VERITY
  - wqueue09 tests WATCH_META_LOSS_NOTIFICATION event
  - wqueue08 tests WATCH_META_REMOVAL_NOTIFICATION event
  - wqueue07 tests NOTIFY_KEY_SETATTR event
  - wqueue06 tests NOTIFY_KEY_CLEARED event

* Increased coverage
  - fanotify14, fanotify16: Add tests for FAN_REPORT_TARGET_FID and FAN_RENAME
  - futex_waitv01: Add test verifies EINVAL for invalid nr_futexes
  - getcontext01: Test rewritten so that it actually jumps back
  - fstat02: Validate st_nlink as well
  - sched_get_priority_max01, sched_get_priority_min01: Add missing policies

* KVM library was written for LTP
  - a simple library that can spin up a VM and execute payload
  - see also https://github.com/linux-test-project/ltp/wiki/KVM-Test-API

* The concept of test runtime was introduced
  - for details see https://people.kernel.org/metan/test-timeout-and-runtime

* Removed tests
  - syslog tests as these were testing mostly userspace syslog daemon
    and were broken for most of the syslog daemon implementations

* The test library was fixed to terminate all leftover processes in the case
  that the main test process dies or exits

* New sparse check for {} terminator for struct arrays in tst_test has been
  implemented

* Shell library improvements
  - added support for $TST_FORMAT_DEVICE (.format_device in C API)
  - preparations for shell API get support for testing on all filesystems (.all_filesystems in C API)
  - getopts cleanup and changes how is the library sources,
    which resulted in much simpler library code

* Userns tests were rewritten into the new test API

* Mountns tests were rewritten into the new test API

* 33 tests were rewritten to the new library

+ The usual amount of fixes and cleanups

WHAT IS IN THE QUEUE
====================

In-flight patches include:

- CGroup shell test rewrite that should fix many problems


NOTABLE CHANGES IN NETWORK TESTS
================================
brought to you by Petr Vorel

* Several fixes (e.g. important nfs_lib: Fix fsid randomisation)

* Ongoing discussion where should be SCTP testsuite home
