Dear RT folks!
I'm pleased to announce the v5.14.1-rt19 patch set.
Changes since v5.14.1-rt18:
- Dan Carpenter reported a possible NULL pointer dereference in
rt_mutex_adjust_prio_chain(). Patch by Peter Zijlstra.
- Unused rt_rwlock_is_contended() has been removed. Reported by kernel
test robot.
- The "play idle" timer was missing a _HARD annotation. It would
freeze the system uppon activation of the intel powerclamp driver.
Reported by Thomas Gleixner.
- Vlastimil Babka SLUB queue has been updated to v6r2.
Known issues
- netconsole triggers WARN.
- The "Memory controller" (CONFIG_MEMCG) has been disabled.
- A RCU and ARM64 warning has been fixed by Valentin Schneider. It is
still not clear if the RCU related change is correct.
- Clark Williams reported issues in i915 (execlists_dequeue_irq())
- Valentin Schneider reported a few splats on ARM64, see
https://https://lkml.kernel.org/r/.kernel.org/lkml/20210810134127.1394269-1-valentin.schneider@arm.com/

Dear RT folks!
I'm pleased to announce the v5.14-rc6-rt10 patch set.
Changes since v5.14-rc6-rt9:
- The locking bits haven been updated updated by Thomas Gleixner. They
have been posted as v5 to the list.
- The patches for locking's API selftest have been updated. As a
result the locking selftest can be enabled.
Known issues
- netconsole triggers WARN.
- The "Memory controller" (CONFIG_MEMCG) has been disabled.
- A RCU and ARM64 warning has been fixed by Valentin Schneider. It is
still not clear if the RCU related change is correct.
- Clark Williams reported issues in i915 (execlists_dequeue_irq())
- Clark Williams reported issues with kcov enabled.
- Valentin Schneider reported a few splats on ARM64, see
https://https://lkml.kernel.org/r/.kernel.org/lkml/20210810134127.1394269-1-valentin.schneider@arm.com/
- PPC64 does not build (due to atomic header includes).
- Clark Williams reported a crash in the SLUB memory allocator. It does
not look like a recent regression and might been there since the SLUB
rework started in v5.13-rt1.

Dear RT folks!
I'm pleased to announce the v5.14-rc4-rt4 patch set.
Changes since v5.14-rc4-rt3:
- Updating the locking bits:
- Use proper task state in ww_mutex_lock_interruptible(), reported
by Mike Galbraith.
- Fix the wake_q handling for a task which blocks simultaneously as
a regular task and additionally as a sleeper on a sleeping lock.
Regression introduced in the v5.14 cycle, reported by Mike
Galbraith, patched by Thomas Gleixner.
- Address the futex related review comments by Peter Zijlstra.
Known issues
- netconsole triggers WARN.
- The "Memory controller" (CONFIG_MEMCG) has been disabled.
- A RCU and ARM64 warning has been fixed by Valentin Schneider. It is
still not clear if the RCU related change is correct.

Dear RT folks!
I'm pleased to announce the v5.14-rc3-rt1 patch set.
Changes since v5.13-rc3-rt1:
- Update to v5.14-rc3
- Update the locking bits.
- Update the mm/slub bits from Vlastimil Babka. The SLUB_CPU_PARTIAL
can now be enabled/ disabled. There is a significant hackbench
related regression due to the rework compared to the old SLUB bits
we had. However I haven't seen anything in real-world workload. If
there is anything, please let me know.
- The "Memory controller" (CONFIG_MEMCG) has been disabled due to
optimisations which it received as it made it incompatible with
PREEMPT_RT.
- A RCU and ARM64 warning has been fixed by Valentin Schneider. It is
still not clear if the RCU realted change is correct.
- A fix for a ARM64 regression which popped up in the v5.13 released
that led to a freeze while starting the init process.
Known issues
- netconsole triggers WARN.
You can get this release via the git tree at:
