Generic semaphore implementation 2008-04-17T14:42:34+00:00 Matthew Wilcox matthew@wil.cx 2008-03-08T02:55:58+00:00 64ac24e738823161693bf791f87adc802cf529ff Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility. Thanks to Peter Zijlstra for fixing the lockdep warning. Thanks to Harvey Harrison for pointing out that the unlikely() was unnecessary.

Well, except for one in libusual that the maintainer explicitly wants to keep as semaphore. So convert that useage to an explicit sema_init and kill of DECLARE_MUTEX_LOCKED so that new code is reminded to use a completion.
