Subject: [RFC PATCH 0/3] locking/mutex: Modifications to mutex
Date: Wed, 4 Jun 2014 12:08:28 -0700 [thread overview]
Message-ID: <1401908911-8947-1-git-send-email-jason.low2@hp.com> (raw)
This patchset contains modifications to mutex.
Patch 1 further reduces unnecessary atomic xchg() operations upon entering
the mutex slowpath in mutex_lock().
Patch 2 corrects/updates the documentation on mutex optimistic spinning.
Patch 3 optimizes mutex trylock slowpath.
Jason Low (3):
mutex: Try to acquire mutex only if it is unlocked
mutex: Correct documentation on mutex optimistic spinning
mutex: Optimize mutex trylock slowpath
