Subject: ceph: only send cap releases when mds is OPEN|HUNG
X-Git-Tag: v2.6.35-rc1~419^2~16
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=aab53dd9e81ccefa7b8d88eec5138dd73639a783;p=linux.git

ceph: only send cap releases when mds is OPEN|HUNG

On OPENING we shouldn't have any caps (or releases).
On CLOSING, we should wait until we succeed (and throw it all out), or
don't (and are OPEN again).
On RECONNECTING we can wait until we are OPEN.
