From f75b1c60fc1e53c4004a79ea0be071aa3318cdcc Mon Sep 17 00:00:00 2001 From: Dave Young Date: Wed, 28 May 2008 09:28:39 -0700 Subject: class: change internal semaphore to a mutex Now that the lockdep infrastructure in the class core is in place, we should be able to properly change the internal class semaphore to be a mutex. David wrote the original patch, and Greg fixed it up to apply properly due to all of the recent changes in this area.
