This is a note to let you know that I've just added the patch titled
usbdevfs: Fix broken scatter-gather transfer
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usbdevfs: Fix broken scatter-gather transfer
The handling of large output bulk transfers is broken; the same user
page is read over and over again. Fixed with this patch.
