documnt FMODE_ constants
commit fc9161e54d0dbf799beff9692ea1cc6237162b85 upstream. Make sure all FMODE_ constants are documents, and ensure a coherent style for the already existing comments. [This is needed for the next patch in the .27 kernel which changes fs.h. This patch makes it easier to handle. - gkh] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
