Is your BLOCK_STATUS series something that is in good enough shape to
post a preliminary version of it (the version you posted back in
February is now horribly out-of-date, with all the good cleanups you
have been doing in the meantime).  I want to get a running start at
reviewing what I can to make sure we get improved NBD functionality into
2.11.

Also, please feel free to offer your Reviewed-by on other patches
(whether NBD-related or not).  Speaking as the NBD maintainer, I welcome
any help I can get.  And from personal experience, reviews tend to be
one of the largest bottlenecks in open source software - if you are
writing patches but not offering reviews, then you are adding to the
bottleneck so reviewers tend to set your patches aside for when they
have more time; while if you are actively offering reviews, then it is
obvious that you care about the project and your patch contributions
tend to have an easier time getting in.  My personal rule of thumb is to
try and review at least 2 other patches for every one that I send,
although that is a rather ambitious goal and there's nothing wrong if
you can't commit to theh same level of effort.

Of course, parts of this will need rebasing based on what finally landed
in 2.10, but I can start reviewing what I can for this round.
