Merge branch 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs
Pull overlayfs fixes from Miklos Szeredi:
"This contains two regression fixes: one for the xattr API update and
one for using the mounter's creds in file creation in overlayfs.
There's also a fix for a bug in handling hard linked AF_UNIX sockets
that's been there from day one. This fix is overlayfs only despite
the fact that it touches code outside the overlay filesystem: d_real()
is an identity function for all except overlay dentries"
* 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:
ovl: fix uid/gid when creating over whiteout
ovl: xattr filter fix
af_unix: fix hard linked sockets on overlay
vfs: add d_real_inode() helper
