[patch 0/2] locking/rtmutex: Cure two subtle bugs

[Thomas Gleixner]

The recent updates to rtmutex introduced two subtle bugs:

  1) The spinwait mechanism added a UAF which triggers a BUG_ON()

  2) The ww_mutex addition leaves a waiter queued in the error exit path
     resulting in rb tree corruption

The fixes are straight forward, but the rtmutex based ww_mutex
implementation still has some more rough egdes which need to be ironed out.

Thanks,
