From 88cf75aaaf27a652b3e85960ac3060172dd3edac Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Fri, 21 Dec 2012 15:07:52 +0400 Subject: [PATCH] CIFS: Fix write after setting a read lock for read oplock files If we have a read oplock and set a read lock in it, we can't write to the locked area - so, filemap_fdatawrite may fail with a no information for a userspace application even if we request a write to non-locked area. Fix this by writing directly to the server and then breaking oplock level from level2 to None. Also remove CONFIG_CIFS_SMB2 ifdefs because it's suitable for both CIFS and SMB2 protocols.
