Dear RT Folks, This is the RT stable review cycle of patch 3.12.38-rt53-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 3/20/2015. I'm only posting the patches that were added since rc1. Enjoy, -- Steve To build 3.12.38-rt53-rc2 directly, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.12.tar.xz http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.12.38.xz http://www.kernel.org/pub/linux/kernel/projects/rt/3.12/patch-3.12.38-rt53-rc2.patch.xz You can also build from 3.12.38-rt52 by applying the incremental patch: http://www.kernel.org/pub/linux/kernel/projects/rt/3.12/incr/patch-3.12.38-rt52-rt53-rc2.patch.xz Changes from 3.12.38-rt52: --- Daniel Wagner (2): work-simple: Simple work queue implemenation thermal: Defer thermal wakups to threads Gustavo Bittencourt (1): rtmutex: enable deadlock detection in ww_mutex_lock functions Josh Cartwright (1): lockdep: selftest: fix warnings due to missing PREEMPT_RT conditionals Kevin Hao (1): netpoll: guard the access to dev->npinfo with rcu_read_lock/unlock_bh() for CONFIG_PREEMPT_RT_FULL=y Mike Galbraith (6): rt: fix __ww_mutex_lock_interruptible() lockdep annotation x86: UV: raw_spinlock conversion scheduling while atomic in cgroup code sunrpc: make svc_xprt_do_enqueue() use get_cpu_light() locking: ww_mutex: fix ww_mutex vs self-deadlock fs,btrfs: fix rt deadlock on extent_buffer->lock Paul E.
