I've got a couple of NFS bkl removal patches queued up that I'll send on
to Linus today, but they will not suffice to fully remove BKL from the
NFS code.
The main remaining problem area is that of file locking (i.e. anything
that references inode->i_flock). I've started work on that, but a couple
of higher interrupts have prevented me from pulling it all together in
time for this merge window...
