overlay filesystem fixes for 3.18

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.

This seems to be the place where overlayfs-fixes are collected for a git-pull request.
Can you add a "T:" line with the Git tree into MAINTAINERS file if this is the case?

Done that already. See "ovl: update MAINTAINERS" patch in that series.

Would you kindly give a firm elaboration of this rename?

Why would a distro kernel maintainer want to keep the external overlayfs patches together with the now in kernel module?

Isn't it enough to drop the external patches from distro kernels in order to use it successfully or are there any semantic changes hidden that an admin should know about?
