If the MDS restarts, the expire caps state is no longer shared, and can be thrown out. Caps state will be rebuilt on the MDS during the reconnect process that follows. Zero out any release messages and adjust the release counter accordingly. Signed-off-by:

The CEPH_FEATURE_NOSRCADDR protocol feature avoids putting the full source address in each message header (twice). This patch switches the client to the new scheme, and _requires_ this feature on the server. The server will support both the old and new schemes. That means an old client will work with a new server, but a new client will not work with an old server. Signed-off-by:

We want to assign an offset when the dentry goes from null to linked, which is always done by splice_dentry(). Notably, we should NOT assign an offset when a dentry is first created and is still null. BUG if we try to splice a non-null dentry (we shouldn't). Signed-off-by:

Since we don't need to maintain large pools of messages, we can just use the standard mempool_t. We maintain a msgpool 'wrapper' because we need the mempool_t* in the alloc function, and mempool gives us only pool_data. Signed-off-by:

ceph_sb_to_client and ceph_client are really identical, we need to dump one; while function ceph_client is confusing with "struct ceph_client", ceph_sb_to_client's definition is more clear; so we'd better switch all call to ceph_sb_to_client. -static inline struct ceph_client *ceph_client(struct super_block *sb) -{ - return sb->s_fs_info; -} Signed-off-by:

If we abort a request, we return to caller, but the request may still complete. And if we hold the dir FILE_EXCL bit, we may not release a lease when sending a request. A simple un-tar, control-c, un-tar again will reproduce the bug (manifested as a 'Cannot open: File exists'). Ensure we invalidate affected dentry leases (as well dir I_COMPLETE) so we don't have valid (but incorrect) leases. Do the same, consistently, at other sites where I_COMPLETE is similarly cleared.
