>Description:
One of my file systems reports fslevel 5.  The fslevels are described
in the fsck_ffs(8) man page, but only for levels 0 through 4.

# dumpfs /build | head 7
file system: /dev/rdk2
format  FFSv2
endian  little-endian
location 65536  (-b 128)
magic   19540119        time    Mon Nov 14 18:24:41 2022
superblock location     65536   id      [ 6303ebb8 4529a702 ]
cylgrp  dynamic inodes  FFSv2   sblock  FFSv2   fslevel 5
# man fsck_ffs
...
          -c level        Convert the FFSv1 file system to the level level.
                           Note that the level of a file system can only be
                           raised.  There are currently five levels defined:

                                 0    The file system is in the old (static
                                      table) format.

...

                                 4    Rearrange the super block to the same
                                      layout as FFSv2; disable the rotational
                                      layout tables and per cylinder group
                                      block totals.  Such file systems are
                                      made by using the -O 1 option to
                                      newfs(8).

                           Note that FFSv2 file systems are always level 4.
