#     
#     Pull AFS fixes from David Howells:
#      "Fixes for AFS plus one patch to make debugging easier:
#     
#        - Fix how addresses are matched to server records. This is currently
#          incorrect which means cache invalidation callbacks from the server
#          don't necessarily get delivered correctly. This causes stale data
#          and metadata to be seen under some circumstances.
#     
#        - Make the dynamic root superblock R/W so that rpm/dnf can reapply
#          the SELinux label to it when upgrading the Fedora filesystem-afs
#          package. If the filesystem is R/O, this fails and the upgrade
#          fails.
#     
#          It might be better in future to allow setxattr from an LSM to
#          bypass the R/O protections, if only for pseudo-filesystems.
#     
#        - Fix the parsing of mountpoint strings. The mountpoint object has to
#          have a terminal dot, whereas the source/device string passed to
#          mount should not. This confuses type-forcing suffix detection
#          leading to the wrong volume variant being mounted.
#     
#        - Make lookups in the dynamic root superblock for creation events
#          (such as mkdir) fail with EOPNOTSUPP rather than something like
#          EEXIST. The dynamic root only allows implicit creation by the
#          ->lookup() method - and only if the target cell exists.
#     
#        - Fix the looking up of an AFS superblock to include the cell in the
#          matching key - otherwise all volumes with the same ID number are
#          treated as the same thing, irrespective of which cell they're in.
#     
#        - Show the volume name of each volume in the volume records displayed
#          in /proc/net/afs/<cell>/volumes. This proved useful in debugging as
#          it provides a way to map the volume IDs to names, where the names
#          are what appear in /proc/mounts"
