Merge branch 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs
Pull overlayfs updates from Miklos Szeredi:
"This update contains:
- try to clone on copy-up
- allow renaming a directory
- split source into managable chunks
- misc cleanups and fixes
It does not contain the read-only fd data inconsistency fix, which Al
didn't like. I'll leave that to the next year..."
