There's a bug in win2k that when NT error codes are not negotiated, the server doesn't response that signatures are mandatory. Since there's (currently) no way turn on signatures in such case, I had to force NT error codes, so that this bug will not occur Signed-off-by: Yehuda Sadeh Weinraub Signed-off-by: Steve French commit 221601c3d1df8148525daf3143a7a22fba772566 Author: Steve French Date: Tue Jun 5 20:35:06 2007 +0000 [CIFS] whitespace cleanup part 2 Various coding style problems found by running the new checkpatch.pl script against fs/cifs. 3 more files fixed up.

Since there were too many to fit in one patch. Updated the first four files.

Because the memory pool still holds some objects and kmem_cache_destroy() says "Can't free all objects".
