Subject: cephfs-tool: set thread names for read/write workers
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=d96e5b148f790c4755cf5f2cf65f9912f01075b6;p=ceph.git

cephfs-tool: set thread names for read/write workers

Set pthread names on all benchmark worker threads (wr-worker-N, rd-worker-N)
via ceph_pthread_setname so they are visible in top, perf, and lockstat
output during profiling.
