Subject: Common/Thread: pthread_attr_destroy(thread_attr) when done with it
X-Git-Tag: v0.80.11~11^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=81bb6dd7de8a191c11c16b3cdc07355ef3434435;p=ceph.git

Common/Thread: pthread_attr_destroy(thread_attr) when done with it
When a thread attributes object is no longer required, it should be destroyed using the
pthread_attr_destroy() function. Destroying a thread attributes object has no effect on threads that were created using that object.

Fixes: #12570

(cherry picked from commit 9471bb838a420ef5f439191d87e5388fecccb9e6)
