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
