ceph: blocklist the kclient when receiving corrupted snap trace
[ Upstream commit a68e564adcaa69b0930809fb64d9d5f7d9c32ba9 ]
When received corrupted snap trace we don't know what exactly has
happened in MDS side. And we shouldn't continue IOs and metadatas
access to MDS, which may corrupt or get incorrect contents.
This patch will just block all the further IO/MDS requests
immediately and then evict the kclient itself.
The reason why we still need to evict the kclient just after
blocking all the further IOs is that the MDS could revoke the caps
faster.
