  review during these two events"

Paulo Alcantara (SUSE) 8eecd1c2e5 cifs: Add support for root file systems
Introduce a new CONFIG_CIFS_ROOT option to handle root file systems
over a SMB share.

In order to mount the root file system during the init process, make
cifs.ko perform non-blocking socket operations while mounting and
accessing it.

Mauro Carvalho Chehab f139291c71 docs: fs: cifs: convert to ReST and add to admin-guide book
The filenames for cifs documentation is not using the same
convention as almost all Kernel documents is using. So,
rename them to a more appropriate name. Then, manually convert
the documentation files for CIFS to ReST.

By doing a manual conversion, we can preserve the original
author's style, while making it to look more like the other
Kernel documents.

Most of the conversion here is trivial. The most complex one was
the README file (which was renamed to usage.rst).

Steve French 876fe8870d documentation update - remove old out of date feature info
Following up on a suggestion by Matthew Wilcox ...

The cifs CHANGES documentation file is out of date, and more
current information is in the wiki.  Delete the old version
information that is of little use to make this documentation
file more readable.

Currently, we have a number of documentation files that live under
fs/cifs/. Generally, these don't get picked up by distro packagers,
since they're in a non-standard location. Move them to a new spot
under Documentation/ instead.
