I may not be the leading BKL expert, but I play one on TV :)

Perhaps one of the kernel-janitor people would like to assist me with
this (cc'ing that list). I'd be willing to keep a web page to list all
current BKL uses and keep track of them as they are removed/added
Perhaps a set of web pages which resemble the directory structure of the
kernel tree would be helpful??

Here's a good question for kernel-janitor, and anyone else who's
interested, what format describing BKL use would most encourage you to
go and remove it? We already have Rick Lindsley's Global spinlock list: . The BKL
use in there is somewhat dated, but might be a good start.

I have some awk scripts that I use on each new kernel release to check
for new and removed uses of the BKL. I can adapt these to start
checking new BK changesets for BKL changes.
