[PULL 47/50] block_job_query: remove atomic read
Posted by Kevin Wolf 2 years, 5 months ago
From: Emanuele Giuseppe Esposito <eesposit@redhat.com>

Not sure what the atomic here was supposed to do, since job.busy
is protected by the job lock. Since the whole function
is called under job_mutex, just remove the atomic.
