Changes since v6.0-rc2-rt3: - Move the defines into Kconfig for do_softirq_own_stack(). - A small clean up of broken of u64_stats_fetch_begin() users. Impacts "only" statistics on 32bit. - Make sure code fails to compile if rwlock.h is included directly. - Update the "Replace PREEMPT_RT ifdefs with preempt_[dis|en]able_nested()." series to v2. - Reorder the softirq code slightly to avoid a sparse warning. Reported by kernel test robot (lkp@intel.com). - Add Vlastimil's "softirq: Redorder the code slightly." series. Known issues - Valentin Schneider reported a few splats on ARM64, see https://lkml.kernel.org/r/20210810134127.1394269-1-valentin.schneider@arm.com The delta patch against v6.0-rc2-rt3 is appended below and can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.0/incr/patch-6.0-rc2-rt3-rt4.patch.xz You can get this release via the git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v6.0-rc2-rt4 The RT patch against v6.0-rc2 can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.0/older/patch-6.0-rc2-rt4.patch.xz The split quilt queue is available at: https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.0/older/patches-6.0-rc2-rt4.tar.xz Sebastian Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dear RT folks! I'm pleased to announce the v5.18-rt11 patch set. Changes since v5.18-rt10: - Dropping preempt_check_resched_rt() checks. The checks were added to ensure a possible wake up which could be missed if the wakeup happens on the same CPU with disabled interrupts. This has been reduced to a ksoftirqd wake and is no longer needed because a softirq-raise won't wake ksoftirqd if the caller has BH disabled. The remaining two caller (based on audit, htb_work_func() and dev_cpu_dead()) acquire/release a lock "soon" which provides the needed scheduling point.

Changes since v5.18-rc5-rt4: - Replace the ptrace patch with v4 of Eric W. Biederman's rework plus a smaller patch on top to get it to work. - Drop get_cpu_light from the series: - Replace the crypto/cryptd patch with an alternative version. - Replace the nfs/sunrpc patch with an alternative version. - Replace the vmalloc related patch with an alternative version. - Replace the block-mq related patch with an alternative version. - Replace the scsi/fcoe patch with two patches by Davidlohr Bueso plus two additional patches in order to tackle two remaining issues in that area. - Drop the preempt-disable -> migrate-disable replacement in kvm on arm64. It seems no longer to be needed. - Drop the "delay sending signals in atomic context" on x86/arm64. It is not needed to send a SIGTRAP for a breakpoint on x86 (the original motivation). Lets see if something else pops up. This might break ARM64 in that regard and will be investigated in a follow up release.

Changes since v5.17-rc6-rt10: - Update the delayed signal patch for x86. The functionality is unchanged. Update by Thomas Gleixner. - Delay the fast init of the random pool to a worker. This was accidentally removed from the last release. Upstream has a slightly different solution for that but has too many dependency for a backport. - Drop the special handling of preempt_enable_no_resched() on PREEMPT_RT. There are almost no users left so it is not worth the trouble. - Update the "ptrace: fix ptrace vs tasklist_lock race" patch. The functionality is unchanged. - Don't delay the RCU selftest at boot and try a different approach.
