[Bug 548546] Re: Nautilus does not remove usb drive made with USB-Creator after unmounting it

[Stefan Bader]

The patch to fix the issue currently is queued in linux-next:

commit 23e2632cc815fb6cc38560805a12be586e23a8f1
Author: Phillip Susi <psusi at cfl.rr.com>
Date:   Sat Jul 16 23:31:06 2011 +1000

    Fix the loopback device to emit a uevent on auto release.  The loopback
    driver failed to emit the change uevent when auto releasing the device.
    Fix lo_release() to pass the bdev to loop_clr_fd() so it can emit the
    event.

As the merge window has opened, it should likely get into 3.1 from where
we could pick it. I am no sure Ayan's patch would make it (sure one
could try to send it upstream (after removing the unnecessary whiespace
change)) upstream. From the lo_ioctl side bdev is the known (passed in
argument) while lo is not. Theoretically clear could be called before
set and that may or may not be checked for under all circumstances.
