Subject: [GIT PULL] readlink cleanup

Hi Al,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git readlink

This is a rework of the readlink cleanup patchset.  Now readlink(2) does the
following:

 - if i_op->readlink() is non-NULL (only proc and afs mountpoints for now) then
   it calls that;
 - otherwise call i_op->get_link();
 - signature of ->readlink() now matches that of ->get_link();

This is against the #misc branch (the stats look better that way ;)

Thanks,
Miklos

Miklos Szeredi (10):
      ecryptfs: use vfs_get_link()
      proc/self: use generic_readlink
      vfs: replace calling i_op->readlink with vfs_readlink()
      vfs: default to generic_readlink()
      vfs: remove ".readlink = generic_readlink" assignments
      vfs: make generic_readlink() static
      vfs: convert ->readlink to same signature as ->get_link
      vfs: remove page_readlink()
      vfs: make readlink_copy() static
      nsfs: clean up ns_get_name() interface
