Default kpartx return codes

I noticed some issues with kpartx return codes:

On an unconnected loop device we get warnings,
but an EXIT_SUCCESS ?

# kpartx -a /dev/loop1 && echo EXIT_SUCCESS
read error, sector 0
llseek error
llseek error
llseek error
EXIT_SUCCESS

Also for a loop device that is connected,
I get a "failed" warning, but the EXIT_SUCCESS
is appropriate in that case as the mapped device
is present and usable

# kpartx -a /dev/loop0
/dev/mapper/loop0p1: mknod for loop0p1 failed: File exists

cheers,
Pádraig.

p.s. the git repo on kernel.org is no longer available

I was kinda waiting for that before attempting to look at the above issues.

cheers,

Sorry for not advertizing more.
