[ANNOUNCE] v4.19-rt1v4.19-rt1-patches
Dear RT folks!
I'm pleased to announce the v4.19-rt1 patch set.
Changes since v4.18.16-rt9:
- rebase to v4.19
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.
You can get this release via the git tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v4.19-rt1
