[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.
