#
# filter out counts which will vary
#   - extsz, blocks, agsize, agcount, device name, rtextents
#   - log version varies for crc enabled fs
#   - lsunit varies for 512/4k sector devices
# filter out differences between linux and irix:
#   - sectsz on Linux
#   - mmr, mixed-case on IRIX
#   - lazy-count on IRIX
#   - inode-paths on IRIX
#   - trailing spaces on Linux but not on IRIX
#
# Example output:
#  meta-data=DEV isize=256    agcount=N, agsize=N blks
#  data     =                       bsize=4096   blocks=N, imaxpct=25
