Description of problem:
I find it useful to be able to create a large loopback root filesystem.  Unfortunately nash losetup fails when attempting to create a loopback device for a file >= 2 GB in size.


Version-Release number of selected component (if applicable):
mkinitrd-4.2.15-1

How reproducible:
Always

Steps to Reproduce:
Example:

# dd if=/dev/zero of=testfile bs=1M seek=2048 count=0
# echo losetup /dev/loop0 testfile | /sbin/nash --force
(forcing normal run)
Red Hat nash version 4.2.15 starting
losetup: failed to open testfile: 27


Expected Results:  Running the same test with seek=2047 instead of 2048 works fine.

Additional info:

The util-linux losetup has no problem handling large files.
