Hey Linus,
/* Summary */
This contains Sebastian's fix to make changing mount attributes/getting write
access compatible with CONFIG_PREEMPT_RT. The change only applies when users
explicitly opt-in to real-time via CONFIG_PREEMPT_RT otherwise things are
exactly as before. We've waited quite a long time with this to make sure folks
could take a good look.
/* Testing */
All patches are based on v5.16-rc2 and have been sitting in linux-next. No
build failures or warnings were observed and fstests and selftests have seen no
regressions caused by this patchset.
/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with current
mainline.
The following changes since commit 136057256686de39cc3a07c2e39ef6bc43003ff6:
