2013-01-02CIFS: Don't let read only caching for mandatory byte-range locked filesPavel Shilovsky
If we have mandatory byte-range locks on a file we can't cache reads because pagereading may have conflicts with these locks on the server. That's why we should allow level2 oplocks for files without mandatory locks only.

2012-12-30cifs: adjust sequence number downward after signing NT_CANCEL requestJeff Layton
When a call goes out, the signing code adjusts the sequence number upward by two to account for the request and the response. An NT_CANCEL however doesn't get a response of its own, it just hurries the server along to get it to respond to the original request more quickly. Therefore, we must adjust the sequence number back down by one after signing a NT_CANCEL request.

2012-09-28cifs: obtain file access during backup intent lookup (resend)Shirish Pargaonkar
Rebased and resending the patch. Path based queries can fail for lack of access, especially during lookup during open. open itself would actually succeed becasue of back up intent bit but queries (either path or file handle based) do not have a means to specifiy backup intent bit. So query the file info during lookup using trans2 / findfirst / file_id_full_dir_info to obtain file info as well as file_id/inode value.
