Subject: mutex: handle gracefully if a PTHREAD_PRIO_INHERIT protocol cannot be set
X-Git-Tag: v1.99.1~89
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9a92327c27a5a321fd15274fb5b1b180e5417a74;p=platform%2Fupstream%2Fpulseaudio.git

mutex: handle gracefully if a PTHREAD_PRIO_INHERIT protocol cannot be set

This adds an additional check for unavailable PTHREAD_PRIO_INHERIT to the
fallback work done in ca717643ee768307475fc36ea29d920a13db0a8e

See bug #42715
