[GIT PULL] overlay filesystem fixes for 3.18

[Miklos Szeredi]

Hi Al,

Please pull from

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-current

The biggest change is to rename the filesystem from "overlayfs" to "overlay".
This will allow legacy overlayfs to be easily carried by distros alongside the
new mainline one.  Also fix a couple of copy-up races and allow escaping comma
character in filenames.

Thanks,
Miklos
