cifs: Allow directIO read/write during cache=strict
Currently cifs have all or nothing approach for directIO operations. cache=strict mode does not allow directIO while cache=none mode performs all the operations as directIO even when user does not specify O_DIRECT flag. This patch enables strict cache mode to honour directIO semantics.
