has been added to the -mm tree. Its filename is

out what to do about this
------------------------------------------------------
Subject: Pass sparse the lock expression given to lock annotations
From: Josh Triplett <josht@xxxxxxxxxx>
The lock annotation macros __acquires, __releases, __acquire, and __release
all currently throw the lock expression passed as an argument. Now that
sparse can parse __context__ and __attribute__((context)) with a context
expression, pass the lock expression down to sparse as the context
expression.
