Subject: [PATCH] mm: remove unused TestSetPageLocked() interface
Date: Thu, 17 Feb 2011 18:08:32 -0800 [thread overview]
Message-ID: <1297994912-27555-1-git-send-email-walken@google.com> (raw)
TestSetPageLocked() isn't being used anywhere. Also, using it would
likely be an error, since the proper interface trylock_page() provides
stronger ordering guarantees.
