Please mail umsdos-related things to me (
I'd add pointer to MAINTAINERS in next patch (I've only rememberd CREDITS
last time).

Also, you may find fs/umsdos/README-WIP.txt containing some other useful

will be in 2.1.103:

Yes, I know about those two. I'd left them there to remind me I need to
check this... :-)

Thanks, my gcc missed this typo. Patch is ok, will be incorporated in next
