Dear RT folks!
I'm pleased to announce the v4.6.4-rt7 patch set.
Changes since v4.6.4-rt6:
- Wake up all waiters of del_timer_sync(). Usually there should not
be more than just one waiter (per timer base) but it possible to
gain more.
- Wake up the waiters of del_timer_sync() after dropping the base lock.
Known issues
- CPU hotplug got a little better but can deadlock.
The delta patch against 4.6.4-rt6 is appended below and can be found here:
https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.6/i...
You can get this release via the git tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v4.6.4-rt7
The RT patch against 4.6.2 can be found here:
