[PATCH] pi-futex: rt mutex docs Add rt-mutex documentation. [rostedt@goodmis.org: Update rt-mutex-design.txt as per Randy Dunlap suggestions] Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Cc: "Randy.Dunlap" <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

rtmutex: update rt-mutex The rtmutex remove a pending owner bit in in rt_mutex::owner, in commit 8161239a8bcc ("rtmutex: Simplify PI algorithm and make highest prio task get lock") But the document was changed accordingly. Updating it to a meaningful state. BTW, as 'Steven Rostedt' mentioned: There is still technically a "Pending Owner", it's just not called that anymore. The pending owner happens to be the top_waiter of a lock that has no owner and has been woken up to grab the lock.
