Bug#463769: Fails on files (ie disk images)

[Wakko Warner]

Package: mdadm
Version: 2.6.4-1
Severity: minor
Tags: patch

I made an image of 2 disks that are part of a 2 disk raid0.  These images are
320gb in size.  I tried to use mdadm -E to give me some information about
them which resulted in:
# mdadm -E /junk/nail.md0-part1of2.img
mdadm: cannot open /junk/nail.md0-part1of2.img: File too large
# 

I modified the source to use O_LARGEFILE in open which gave me an error
stating that the "device" was not recognised.  mdadm does not stat files to
obtain the size, it only uses ioctl's.  The patch adds O_LARGEFILE and tests
to see if the device is a file and uses that information instead.

This worked for me, but I only modified for -Q and -E.  I did not attempt to
assemble the array.
