Subject: [PATCH 0/4] [RFC] 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.

I tested the fuse part, but not the other filesystems (AFS, GFS2, NFS, SYSFS).
The changes to filesystems are pretty trivial, though.

Thanks,
Miklos

      fuse: drop dentry on failed revalidate

Miklos Szeredi (3):
      vfs: check submounts and drop atomically
      vfs: check unlinked ancestors before mount
      fuse: use d_materialise_unique()
