From: Yan, Zheng Date: Mon, 19 Nov 2012 02:49:09 +0000 (+0800) Subject: ceph: call handle_cap_grant() for cap import message X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0e5e1774a92e6fe9c511585de8f078b4c4c68dbb;p=linux-beck.git ceph: call handle_cap_grant() for cap import message If client sends cap message that requests new max size during exporting caps, the exporting MDS will drop the message quietly. So the client may wait for the reply that updates the max size forever. call handle_cap_grant() for cap import message can avoid this issue.
