Subject: [PATCH v12 19/21] block_job_query: remove atomic read
Date: Mon, 26 Sep 2022 05:32:12 -0400 [thread overview]
Message-ID: <20220926093214.506243-20-eesposit@redhat.com> (raw)
In-Reply-To: <20220926093214.506243-1-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.
