[PATCH v2 0/2] rtmutex wait_lock is irq safe
From: Anna-Maria Gleixner
Date: Fri May 25 2018 - 08:00:01 EST
Since commit b4abf91047cf ("rtmutex: Make wait_lock irq safe") the rtmutex
wait_lock is irq safe. Therefore the irqsave/restore in kernel/signal is no
longer required (see Patch 2/2). During discussions about v1 of this patch,
Eric Biederman noticed, that there is a no longer valid rcu_read_unlock()
documentation.
Therefore sending a short queue: fixing first the documentation of
rcu_read_unlock() and afterwards removing irqsave/restore in kernel/signal.
v1..v2:
- Add new patch updating rcu documentation as suggested by Eric Biederman
- Udpate commit message of kernel/signal patch
Thanks,
Anna-Maria
