[PATCH] mutex subsystem, semaphore to completion: IDE ->gendev_rel_sem
The patch changes semaphores that are initialized as locked to complete(). Source: MontaVista Software, Inc. Modified-by: Steven Rostedt <rostedt@goodmis.org> The following patch is from Montavista. I modified it slightly. Semaphores are currently being used where it makes more sense for completions. This patch corrects that.
