Documentation/filesystems/xfs.txt:

  logbsize=value
        Set the size of each in-memory log buffer.  The size may be
        specified in bytes, or in kilobytes with a "k" suffix.
        Valid sizes for version 1 and version 2 logs are 16384 (16k)
        and 32768 (32k).  Valid sizes for version 2 logs also
        include 65536 (64k), 131072 (128k) and 262144 (256k). The
        logbsize must be an integer multiple of the log
        stripe unit configured at mkfs time.
