Subject: rgw: nfs: disable gc, lc, quota, and sync threads by default
X-Git-Tag: v15.2.5~56^2~7
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=78821f17159bb39a99f2cf84e94968a125c00206;p=ceph.git

rgw: nfs: disable gc, lc, quota, and sync threads by default

These can be overridden by new options, should a site decide to
run a librgw with no radosgw instances.
