Bug#860894: kpartx: kpartx returns error even when loop device is deleted successfully

[Balint Reczey]

Package: kpartx
Version: 0.6.4-5
Severity: wishlist
Tags: patch

Dear Maintainers,

Sometimes kpartx reports errors during handling partition while at the
end deleting the loop device succeeds:

$ kpartx -v -d binary/boot/disk-uefi.ext4
device-mapper: remove ioctl on loop0p1 failed: Device or resource busy
del devmap : loop0p15
del devmap : loop0p14
loop deleted : /dev/loop0
$
# here we have $? != 0
# (from: https://bugs.launchpad.net/ubuntu/+source/livecd-rootfs/+bug/1684090)

Please find the patch attached which ignores earlier errors after loop
deletion is done.

Cheers,
Balint
