Bug #6427: ruby ioctl: Error integer 2148012656 too big to convert to `int'

Hi,

the upgrade to ubuntu 12.04 came with an upgrade to ruby 1.9.3.
Unfortunately, in recent 1.9.3 versions of ruby there's a bug in the
ioctl function. E.g. if you want to do getbsz() on a block device and do
a

f.ioctl(0x80081270,a)

you'll get the error message

Error integer 2148012656 too big to convert to `int'
RangeError

(2148012656 = 0x80081270)

So ruby can't do ioctl's anymore if the highest bit is set in the ioctl code. 

This was working code in ruby 1.9.2 / ubuntu 11.10.


regards
