PR 1124/rtems
* score/include/rtems/score/threadq.h, score/src/coremutexseize.c,
score/src/coremutexsurrender.c, score/src/threadqenqueue.c,
score/src/threadqenqueuefifo.c, score/src/threadqenqueuepriority.c:
The placement of the changing a thread's priority when using priority
ceiling should be on the successful transfer of the mutex -- not when
the thread tries to acquire. Plus the lack of a dispatch disable
point lead to the potential for a thread timing out and already
having inherited the ceiling priority.
