-Subject: [PATCH] Fix use of __pthread_attr_copy in mq_notify (bug 27896)
-
-__pthread_attr_copy can fail and does not initialize the attribute
-structure in that case.
-
-If __pthread_attr_copy is never called and there is no allocated
-attribute, pthread_attr_destroy should not be called, otherwise
-there is a null pointer dereference in rt/tst-mqueue6.
-
-Fixes commit 42d359350510506b87101cf77202fefcbfc790cb
-("Use __pthread_attr_copy in mq_notify (bug 27896)").
