Dear RT folks!
I'm pleased to announce the v4.14.12-rt10 patch set.
Changes since v4.14.8-rt9:
- updated to v4.14.12
- An additional include to avoid a build failure on ARM after a header
disappeared somewhere during the stable update.
- The patch "nohz: Prevent erroneous tick stop invocations" was merged
differently upstream. The original issue where a slow box could lock up
with a pending timer remained. I currently assume that this is a RT only
issue and keep the patch as RT only.
Known issues
- A warning triggered in "rcu_note_context_switch" originated from
SyS_timer_gettime(). The issue was always there, it is now
visible. Reported by Grygorii Strashko and Daniel Wagner.
