#     afs: Fix characters allowed into cell names
#     
#     The afs filesystem needs to prohibit certain characters from cell names,
#     such as '/', as these are used to form filenames in procfs, leading to
#     the following warning being generated:
#     
#             WARNING: CPU: 0 PID: 3489 at fs/proc/generic.c:178
#     
#     Fix afs_alloc_cell() to disallow nonprintable characters, '/', '@' and
#     names that begin with a dot.
#     
#     Remove the check for "@cell" as that is then redundant.
#     
#     This can be tested by running:
#     
#             echo add foo/.bar 1.2.3.4 >/proc/fs/afs/cells
#     
#     Note that we will also need to deal with:
#     
#      - Names ending in ".invalid" shouldn't be passed to the DNS.
#     
#      - Names that contain non-valid domainname chars shouldn't be passed to
#        the DNS.
#     
#      - DNS replies that say "your-dns-needs-immediate-attention.<gTLD>" and
#        replies containing A records that say 127.0.53.53 should be
#        considered invalid.
#        [https://www.icann.org/en/system/files/files/name-collision-mitigation-01aug14-en.pdf]
#     
#     but these need to be dealt with by the kafs-client DNS program rather
#     than the kernel.
