Can you post the full URL for this, and maybe give us a teaser on what
to expect?  I run lvache on my home system and I'd love to know how to
A) improve reporting of how well it works, and B) whether I'm using it
right, and of course C) if bcache would be a better replacement.

I'm using Linux v5.0.21 (self compiled) on Debian 9.11 with lvcache
setup.  It's a pair of mirrored 250gb SSDs in front of 4tb of mirrored
disk.

So anything where I can use my SSDs to cache my data accesses is
certainly interesting.
