Subject: client: don't update i_max_size when handle reply from non-auth MDS
X-Git-Tag: v0.79~179^2~14
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=154efb153427a0068507e09663c12a56afa15dc2;p=ceph.git

client: don't update i_max_size when handle reply from non-auth MDS

caps from non-auth mds don't have meaningful max_size
