Subject: Re: [PATCH] max_loop limit, loop.c final working version

This is a diff from Ken Chen, who sent it to me a week ago and received 
the claimed prize $256. I think it's partially based on Jan's code, 
while if fixes the bug Jan mentioned (as far as I know).

It does the following:
- allocate loop dynamically on the fly
- allocate one more (spare) loop each time,
   so losetup and mount tools can work correctly
- doesn't need any module parameters

Unfortunately 'mount' and 'losetup' binaries are hardcoded to stop 
searching for free loop device after the minor num 255, so one have to 
use a workaround in order to use more loops with 'mount':

$ losetup /dev/loop1000 file
$ mount /dev/loop1000 /mntpnt

I hope these binaries will be fixed soon.
