Subject: rgw: data shard sync doesn't exit on error
X-Git-Tag: v10.1.0~72^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=70ca604fb50e40527714e1c62c6a0d166433d645;p=ceph.git

rgw: data shard sync doesn't exit on error

We don't handle the error at the top level, so no
need to exit. Just continue with the backoff mechanism.
