[GIT PULL] vfs prep for overlayfs update

[Miklos Szeredi]

Hi Al,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git vfs-ovl

These are the bits of the upcoming overlayfs update that touch vfs/mm/af_unix.

 - Revert d_real_inode() comparisons that became obsolete;
 - add support for clone on copy-up;
 - add support for consistency of read/mmap after copy-up.

Thanks,
Miklos
