Subject: [PATCH v2 0/4] MCS Lock: MCS lock code cleanup and optimizations
Date: Tue, 05 Nov 2013 09:42:26 -0800	[thread overview]
Message-ID: <1383673346.11046.276.camel@schen9-DESK> (raw)
In-Reply-To: <cover.1383670202.git.tim.c.chen@linux.intel.com>

In this patch series, we separated out the MCS lock code which was
previously embedded in the mutex.c.  This allows for easier reuse of
MCS lock in other places like rwsem and qrwlock.  We also did some micro
optimizations and barrier cleanup.

This patches were previously part of the rwsem optimization patch series
but now we spearate them out.

Tim Chen

v2:
1. change export mcs_spin_lock as a GPL export symbol
2. corrected mcs_spin_lock to references


Jason Low (2):
  MCS Lock: optimizations and extra comments
  MCS Lock: Barrier corrections

Tim Chen (1):
  MCS Lock: Restructure the MCS lock defines and locking code into its
    own file

Waiman Long (1):
  MCS Lock: Make mcs_spinlock.h includable in other files
