- Subject: [PATCH] Add PTHREAD_MUTEX_NORMAL_INT
From: Andi Kleen <ak@linux.intel.com>
Carlos asked for PTHREAD_MUTEX_NORMAL_INT to be added
to make some of the internal macros be easier to understand.
It is always identical to DEFAULT, as NORMAL only makes
a difference for settype.
2013-06-24 Andi Kleen <ak@linux.intel.com>
* pthreadP.h (PTHREAD_MUTEX_NORMAL_INT): Add and use
for PTHREAD_MUTEX_PP_{PI,NORMAL}_NP .
