Permalink
This patchset includes various cleanups that touch open codepath. This will help to introduce share modes into cifs module easier.

Patches are rebased on top of Sachin's patchset "Clean up MF-Symlink code and add readlink support for DFS shares".

Pavel Shilovsky (4):
CIFS: Cleanup CIFSSMBOpen
CIFS: Cleanup cifs_mknod
CIFS: Remove extra indentation in cifs_sfu_type
CIFS: Cleanup cifs open codepath

Remove indentation, fix comment style, rename camel case
variables in preparation to make it work with cifs_open_parms
structure as a parm.

looks reasonable but am getting various minor whitespace errors
scanning the patch series

Can you fixup and make sure it is checkpatch clean?

e.g.

ERROR: trailing whitespace
#123: FILE: fs/cifs/dir.c:650:
+^I/*^M$

ERROR: trailing whitespace
#124: FILE: fs/cifs/dir.c:651:
+^I * BB Do not bother to decode buf since no local inode yet to put^M$

ERROR: trailing whitespace
#125: FILE: fs/cifs/dir.c:652:
+^I * timestamps in, but we can reuse it safely.^M$

Steve, are you sure you got right variants? I tested my patches with
checkpatch.pl and everything was ok. I applied them on top of your
current for-next branch and attached.

Those four that you just sent checkpatch clean.

Merged into cifs-2.6.git

Any additional Reviewed-by would be appreciated for those 4.
