Subject: [ 213/221] ceph: Dont update i_max_size when handling non-auth cap

3.7-stable review patch.  If anyone has any objections, please let me know.

------------------


From: "Yan, Zheng" <zheng.z.yan@...el.com>

(cherry picked from commit 5e62ad30157d0da04cf40c6d1a2f4bc840948b9c)

The cap from non-auth mds doesn't have a meaningful max_size value.
