md has hard coded maximum number of drives?

# mdadm --create /dev/md0 --level 0 --raid-devices 60 `cat drives`
mdadm: invalid number of raid devices: 60

# mdadm --create /dev/md0 --level 0 --raid-devices 32 `cat drives`
mdadm: invalid number of raid devices: 32

# mdadm --create /dev/md0 --level 0 --raid-devices 33 `cat drives`
mdadm: invalid number of raid devices: 33



Firstly, "invalid number" is a terrible error message. 60 is a perfectly good
number. The error message gives no indication of why it doesn't find 60 to be
a "valid" number.


Secondly there's no mention in any documentation for mdadm or anywhere else
that I can find of any arbitrary maximum number of drives.


Thirdly, WTF?!
