2012-03-20NFS: Use cond_resched_lock() to reduce latencies in the commit scansTrond Myklebust
Ensure that we conditionally drop the inode->i_lock when it is safe to do so in the commit loops. We do so after locking the nfs_page, but before removing it from the commit list. We can then use list_safe_reset_next to recover the loop after the lock is retaken. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-03-20NFSv4: It is not safe to dereference lsp->ls_state in release_lockownerTrond Myklebust
It is quite possible for the release_lockowner RPC call to race with the close RPC call, in which case, we cannot dereference lsp->ls_state in order to find the nfs_server. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-03-20NFS: ncommit count is being double decrementedFred Isaman
The decrement is handled by each call to nfs_request_remove_commit_list, no need to do it again in nfs_scan_commit. Signed-off-by: Fred Isaman <iisaman@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-03-20CIFS: Respect negotiated MaxMpxCountPavel Shilovsky
Some servers sets this value less than 50 that was hardcoded and we lost the connection if when we exceed this limit. Fix this by respecting this value - not sending more than the server allows.
