I am also looking at kvblade. I had to make some minor adjustments to
get it to work with a more recent kernel. Those crazy kernel guys love
re-naming things.

As soon as I have a chance to dig through git and find out where things
changed, I'll send a patch so that make just works for old and new. I
don't subscribe to LKML, its just too much noise, I just read the
changelogs for every rc.

I will send a patch for that, its trivial. Only a few entries so that
nice and logger options can be controlled.

Exploiting vblade's rudimentary options for access control also comes to
mind, but that is not best implemented in a default configuration.

In short, I'll soon send a patch for the above, and a few more that can
live in the contrib/ directory. For instance, its probably a good idea
for a user space target to use mlockall(). That would help to ensure
benchmarks from a 'cold start' to be consistent. vblade should also have
an option to put it out of the OOM killers reach on start up, depending
on how you use it. Heavy use of DM on a storage server + disk sleep can
cause interesting things to happen, especially with the new LVM2 liblvm
about to emerge in beta.

Cheers,
