So if I understand you correctly you are saying that we should return
the "Not in progress" error code if the filesystem is mounted ro and
there is nothing to cancel. I actually did think about it, but decided
against it because one can extend this argument to starting commands
with something like "If I order a start on a read-only fs and that
operation has already been started, I should get EINPROGRESS.", and
that's not what we are currently doing.
Thanks,
Ilya
