Hello RT folks! This patchset brings back many RT-specific fixes that have gone into subsequent 4.14-rt and 4.16-rt releases. One of my x86 boxes very intermittently triggers a WARN_ON() on bootup in migrate_enable(), which I'm still trying to triage. If you can more reliably reproduce this, please let me know. This release candidate will not be pushed to the git tree. To build 4.9.115-rt94-rc1 directly, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v4.x/linux-4.9.tar.xz http://www.kernel.org/pub/linux/kernel/v4.x/patch-4.9.115.xz http://www.kernel.org/pub/linux/kernel/projects/rt/4.9/patch-4.9.115-rt94-rc1.patch.xz If all goes well with testing, this rc will be promoted to an official release on 8/16/2018. Please go forth and test! Thanks, Julia --- Boqun Feng (1): rtmutex: Make rt_mutex_futex_unlock() safe for irq-off callsites Julia Cartwright (4): locallock: provide {get,put}_locked_ptr() variants squashfs: make use of local lock in multi_cpu decompressor seqlock: provide the same ordering semantics as mainline Linux 4.9.115-rt94-rc1 Paul E.
