hammer cleanup coredumps


From: elekktretterr@xxxxxxxxxxxxxx

This is happening on master.

Steps to reproduce(possibly)

1) Create a couple of pfs-masters inside another pfs like this by accident.

ie hammer pfs-master /usr/something

Receive a warning.

2) rm /usr/something

3) go to /pfs and create symlink to those PFSs you created above.

4) hammer pfs-destroy them

5) now create them properly: hammer pfs-master /pfs/something

6) Mount them

7) Run hammer cleanup

I get this

cleanup /                    - handle PFS #0 using /var/hammer/root
           snapshots - skip
               prune - skip
