Subject: rgw: dont log EBUSY errors in 'sync error list'
X-Git-Tag: v13.0.2~724^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F19580%2Fhead;p=ceph.git

rgw: dont log EBUSY errors in 'sync error list'

these temporary errors get retried automatically, so no admin
intervention is required. logging them only serves to waste space in
omap and obscure the more serious sync errors

Fixes: http://tracker.ceph.com/issues/22473
