In the last git version of kernel, when I copy some data to a USB disk
I got this WARNING:

Since there is no change in drivers/usb/storage/transport.c in the

There's nothing to fix, because nothing is wrong; the warning message
is purely informational. The reason for making it a warning was so
that it would show up in the kerneloops project's records. The warning
itself will be removed before 2.6.29 is released.
Just out of curiousity, what sort of USB disk (vendor and product) are
your 10d6:1101 and 0781:5151 devices?
If you want to get rid of the warning in your own kernel, you can do it
easily enough by removing the WARN() in last_sector_hacks() in
drivers/usb/storage/transport.c.

In fact, Greg, it was _you_ who first suggested making this a WARN! :-)
Never mind. I'll send in a patch to get rid of the warning in a week
or two. Unless people start getting really upset and demand it
sooner...
