Subject: [PATCH 00/10] [v3] safely drop directory dentry on failed revalidate

Here's a series for fixing issues with d_drop on a directory dentry with
children and adding support for such dropped directories in fuse.

This one adds a helper for walking the dentry tree.  This reduces code
duplication and reduces the chances of a bug creeping into one of the instances.

The only user of have_submounts() is now autofs4, but after discussing with Ian
I'm still not sure how we should deal with that.

Thanks,
Miklos

      vfs: add d_walk()
      vfs: check submounts and drop atomically
      vfs: check unlinked ancestors before mount
      afs: use check_submounts_and_drop()
      gfs2: use check_submounts_and_drop()
      nfs: use check_submounts_and_drop()
      sysfs: use check_submounts_and_drop()
      fuse: use d_materialise_unique()
      fuse: clean up return in fuse_dentry_revalidate()
