Subject: [GIT PULL] locking changes for v5.13
Date: Wed, 28 Apr 2021 09:30:07 +0200	[thread overview]
Message-ID: <20210428073007.GA144738@gmail.com> (raw)

Linus,

Please pull the latest locking/core git tree from:

   # HEAD: f4abe9967c6fdb511ee567e129a014b60945ab93 kcsan: Fix printk format string

Locking changes for this cycle were:

 - rtmutex cleanup & spring cleaning pass that removes ~400 lines of code
 - Futex simplifications & cleanups
 - Add debugging to the CSD code, to help track down a tenacious race (or hw problem)
 - Add lockdep_assert_not_held(), to allow code to require a lock to not be held,
   and propagate this into the ath10k driver
 - Misc LKMM documentation updates
 - Misc KCSAN updates: cleanups & documentation updates
 - Misc fixes and cleanups
 - Fix locktorture bugs with ww_mutexes

 Thanks,

	Ingo
