2013-05-05cifs: on send failure, readjust server sequence number downwardJeff Layton
If sending a call to the server fails for some reason (for instance, the sending thread caught a signal), then we must readjust the sequence number downward again or the next send will have it too high.

2013-05-05[CIFS] cifs: Rename cERROR and cFYI to cifs_dbgJoe Perches
It's not obvious from reading the macro names that these macros are for debugging. Convert the names to a single more typical kernel style cifs_dbg macro. cERROR(1, ...) -> cifs_dbg(VFS, ...) cFYI(1, ...) -> cifs_dbg(FYI, ...) cFYI(DBG2, ...) -> cifs_dbg(NOISY, ...) Move the terminating format newline from the macro to the call site. Add CONFIG_CIFS_DEBUG function cifs_vfs_err to emit the "CIFS VFS: " prefix for VFS messages. Size is reduced ~ 1% when CONFIG_CIFS_DEBUG is set (default y) $ size fs/cifs/cifs.ko* text data bss dec hex filename 265245 2525 132 267902 4167e fs/cifs/cifs.ko.new 268359 2525 132 271016 422a8 fs/cifs/cifs.ko.old Other miscellaneous changes around these conversions: o Miscellaneous typo fixes o Add terminating \n's to almost all formats and remove them from the macros to be more kernel style like. A few formats previously had defective \n's o Remove unnecessary OOM messages as kmalloc() calls dump_stack o Coalesce formats to make grep easier, added missing spaces when coalescing formats o Use %s, __func__ instead of embedded function name o Removed unnecessary "cifs: " prefixes o Convert kzalloc with multiply to kcalloc o Remove unused cifswarn macro Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <smfrench@gmail.com>
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.
