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
