[Bug 1124034] [NEW] Cancelling resize operation leaves resize2fs running

[Alan Jenkins]

Public bug reported:

I used GParted to shrink a 400G partition on an external USB3 HD, to
200G.  The filesystem was ext4.

I got bored and annoyed by the lack of a progress indicator.  I clicked
cancel, disregarding the warning that this was a REALLY BAD IDEA :).  I
then closed GParted.

When I tried to fsck the partition, I found that something had an
exclusive lock on the partition.  It turns out that resize2fs was still
running, using CPU and performing IO.  (There are no IO errors in the
kernel log / dmesg).

I can understand if GParted was reluctant to kill resize2fs :).  However
in that case it should have warned that the operation was not actually
cancelled.
