Subject: fix and optimize non-default-type mutex behavior
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=4820f9268d3dc1f2aac923de0a591ffd5d54ea89;hp=4820f9268d3dc1f2aac923de0a591ffd5d54ea89

fix and optimize non-default-type mutex behavior

problem 1: mutex type from the attribute was being ignored by
pthread_mutex_init, so recursive/errorchecking mutexes were never
being used at all.

problem 2: ownership of recursive mutexes was not being enforced at
unlock time.
