2.6.27-stable review patch. If anyone has any objections, please let us know.

------------------

From: Christoph Hellwig <hch@lst.de>

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]
