Dear RT Folks, This is the RT stable review cycle of patch 5.4.74-rt42-rc2. Please scream at me if I messed something up. Please test the patches too. The -rc release will be uploaded to kernel.org and will be deleted when the final release is out. This is just a review release (or release candidate). The pre-releases will not be pushed to the git repository, only the final release is. If all goes well, this patch will be converted to the next main release on 11/11/2020. Changes since -rc1: removed patch: tcp: Remove superfluous BH-disable around listening_hash Enjoy, -- Steve To build 5.4.74-rt42-rc2 directly, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v5.x/linux-5.4.tar.xz http://www.kernel.org/pub/linux/kernel/v5.x/patch-5.4.74.xz http://www.kernel.org/pub/linux/kernel/projects/rt/5.4/patch-5.4.74-rt42-rc2.patch.xz You can also build from 5.4.74-rt41 by applying the incremental patch: http://www.kernel.org/pub/linux/kernel/projects/rt/5.4/incr/patch-5.4.74-rt41-rt42-rc2.patch.xz Changes from 5.4.74-rt41: --- Oleg Nesterov (1): ptrace: fix ptrace_unfreeze_traced() race with rt-lock Sebastian Andrzej Siewior (3): net: Properly annotate the try-lock for the seqlock mm/memcontrol: Disable preemption in __mod_memcg_lruvec_state() timers: Don't block on ->expiry_lock for TIMER_IRQSAFE Steven Rostedt (VMware) (1): Linux 5.4.74-rt42-rc2 ---- include/linux/seqlock.h | 9 --------- include/net/sch_generic.h | 10 +++++++++- kernel/ptrace.c | 23 +++++++++++++++-------- kernel/time/timer.c | 9 ++++++++- localversion-rt | 2 +- mm/memcontrol.c | 2 ++ 6 files changed, 35 insertions(+), 20 deletions(-)
