[2.5.38] loop trying to go beyond end of device

[Burton Windle]

Hello. With the 2.5.38 kernel (preempt enabled), I am getting these errors
when I try to fill up a loop-mounted ext3 or ext2 partition.

The want number starts at 100002, and keeps going up and up and up by 2.

loop(7,2): rw=1, want=100316, limit=100000
attempt to access beyond end of device
loop(7,2): rw=1, want=100318, limit=100000
attempt to access beyond end of device

I can reproduce this with this script:

touch /tmp/foo
mke2fs -j -F /tmp/foo 10000
mkdir /mnt/tmp
mount -o loop /tmp/foo /mnt/tmp
cd /mnt/tmp
dd if=/dev/urandom of=blah

As the partition fills up, I start getting the above message.
