Merge branch 'overlayfs-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs
Pull overlayfs updates from Miklos Szeredi:
"This relaxes the requirements on the lower layer filesystem: now ones
that implement .d_revalidate, such as NFS, can be used.
Upper layer filesystems still has the "no .d_revalidate" requirement.
Also a bad interaction with jffs2 locking has been fixed"
* 'overlayfs-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:
ovl: lookup whiteouts outside iterate_dir()
ovl: allow distributed fs as lower layer
ovl: don't traverse automount points
