switching "balance" into background
Hallo, linux-btrfs,
I can't switch a running "btrfs filesystem balance ..." via
ctrl z
bg
into the background, with other jobs this way works.
The stopping command "ctrl z" doesn't work.
(may be on other keyboards it's "ctrl y")
What goes wrong?
Viele Gruesse!

A balance is a single long-lived ioctl call, so the userspace
process is living in D state (uninterruptible sleep) until the kernel finishes.
I've got a patch that forks the process, and runs the ioctl in the
background, returning immediately. I should be able to get it to the list this weekend as part of the userspace side of the balance management patches.
