I wish my 7 patches made a dent, but it's hasn't done much. ;(

I would guess at least a week just to mop up the relatively easy ones..
I've got 12 in my queue, and there still ~50 hopefully trivial ones
still to be looked at.. Then another ~30 more difficult ones (that use
init_MUTEX_LOCKED, or sema_init with 0 instead of 1) ..
