Subject: [PATCH 0/2] mutex: Modifications to mutex_spin_on_owner
Date: Mon, 2 Feb 2015 13:59:25 -0800 [thread overview]
Message-ID: <1422914367-5574-1-git-send-email-jason.low2@hp.com> (raw)
This patchset contains a few modifications to mutex_spin_on_owner().
The first patch makes the optimistic spinner continue spinning whenever
the owner changes, and the second patch refactors mutex_spin_on_owner()
to micro optimize the code as well as make it simpler.
Jason Low (2):
mutex: In mutex_spin_on_owner(), return true when owner changes
mutex: Refactor mutex_spin_on_owner
