locking/mutexes: Documentation update/rewrite

2014-06-05T11:29:37+00:00

Our mutexes have gone a long ways since the original implementation back in 2005/2006. However, the mutex-design.txt document is still stuck in the past, to the point where most of the information there is practically useless and, more important, simply incorrect. This patch pretty much rewrites it to resemble what we have nowadays. Since regular semaphores are almost much extinct in the kernel (most users now rely on mutexes or rwsems), it no longer makes sense to have such a close comparison, which was copied from most of the cover letter when Ingo introduced the generic mutex subsystem. Note that ww_mutexes are intentionally left out, leaving things as generic as possible.

mutex: Fix annotations to include it in kernel-locking docbook

2010-09-03T06:19:51+00:00

Fix kernel-doc notation in linux/mutex.h and kernel/mutex.c, then add these 2 files to the kernel-locking docbook as the Mutex API reference chapter. Add one API function to mutex-design.txt and correct a typo in that file.
