Patch queue for v4.14.20-rt17
[ANNOUNCE] v4.14.20-rt17
Dear RT folks!
I'm pleased to announce the v4.14.20-rt17 patch set.
Changes since v4.14.20-rt16:
- A RCU warning was disabled if we schedule() while we acquire a
sleeping lock. The warning was still seen on UP only kernels and is
now disabled. Reported by Grygorii Strashko.
- The recording of the recursion limit in networking was changed from
per-CPU to per-task on RT. This was done because BH-context can be
preempted on RT and therefore multiple tasks may attempt to send a
packet and so wrongly increase the counter.
The queue lock owner was still recording the CPU which was holding
the lock instead the task. This will lead to a recursion warning if
the same transmit queue is already used (locked) by another task.
Reported by Kurt Kanzenbach.
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.
