Subject: [PATCH v2 10/10] block/qcow2: Use bdrv_pwrite_sync() in qcow2_mark_dirty()
Date: Fri, 13 May 2022 16:57:49 +0100 [thread overview]
Message-ID: <20220513155749.2488070-8-afaria@redhat.com> (raw)
In-Reply-To: <20220513155418.2486450-1-afaria@redhat.com>
Use bdrv_pwrite_sync() instead of calling bdrv_pwrite() and bdrv_flush()
separately.
