Subject: [PATCH 0/4] [RFC] safely drop directory dentry on failed revalidate
Date: Tue,  6 Aug 2013 16:29:59 +0200	[thread overview]
Message-ID: <1375799403-28544-1-git-send-email-miklos@szeredi.hu> (raw)

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

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