[PATCH] Skip checks in pthread_mutex_destroy when doing elision
When doing elisison the __nusers field is not updated, thus can have an
arbitrary value.

* nptl/pthread_mutex_destroy.c (__pthread_mutex_destroy): Skip
checks when doing elision.
* nptl/sysdeps/unix/sysv/linux/x86/pthread_mutex_destroy.c: New file.
