Filter out PTHREAD_MUTEX_NO_ELISION_NP bit in pthread_mutexattr_gettype (BZ #15790)
|
|
|
ce426f |
|
|
|
ce426f |
pthread_mutexattr_settype adds PTHREAD_MUTEX_NO_ELISION_NP to kind,
|
|
|
ce426f |
which is an internal flag that pthread_mutexattr_gettype shouldn't
|
|
|
ce426f |
expose, since pthread_mutexattr_settype wouldn't accept it.
