So far only clean mode is supported and it is the default mode. In this mode, client drops any dirty data/metadata, invalidates page caches and invalidates all writable file handles. After reconnect, file locks become stale because MDS lose track of them. If an inode contains any stale file lock, read/write on the indoe are not allowed until all stale file locks are released by applications. v2: remove force_remount mount option no enabled auto reconnect by default remove unfinished recover_session=brute codeI've looked over the set and I think this looks reasonable modulo a few small nits that can be cleaned up during or after merging. I don't see the knob that forces a reconnect in this set any longer. Did you decide that that wasn't needed or are you planning to add it in a later set?
add it later Regards Yan, Zheng
