Pointers to archives would have been appreciated.  I can't, for the life
of me, find these.

Thanks for all of the great documentation.  It would be good to include
some instructions on how one would test this, and what testing you
performed.  Also, please use the '-p' switch to diff, as it makes
reviewing patches much easier.

I set out to try your changes, but ran into some problems.  First, this
patch set didn't apply cleanly to a git checkout.  So, I grabbed your
mercurial repository, but got a build failure:

block/blk-core.c: In function 'generic_make_request':
include/linux/bio.h:469: sorry, unimplemented: inlining failed in call to 'bio_i
ntegrity_enabled': function body not available
block/blk-core.c:1388: sorry, unimplemented: called from here
make[1]: *** [block/blk-core.o] Error 1
make: *** [block] Error 2

Cheers,

Jeff
