Another happy user experience: I started packaging bcache-tools for
Fedora 20 summer 2013, just because I wanted to use bcache. After
alligning bcache-tools with util-linux, Dracut and LVM2 (all these
packages needed minor tweaks, that were all integrated upstream) I have
been using bcache myself (of course). I've been living on the edge by
using writeback caching and a cheap SSD, and it has all been working
like a charm! Well, I've been living over the edge actually by
attempting to enable TRIM - I blame the resulting corruptions on the
cheap SSD. And I had occasional "bcache_writeback 100% CPU" issues, but
those seem to be gone (currently kernel 3.16).
And searching for bcache at bugzilla.redhat.com: no bugs pop up. Could
be that there are no bcache users at all, but I know for fact that
that's not true.
So (when not using TRIM): excellent performance and stability. Thanks
for the good work!

If I can throw mine in as well, I've been running bcache on my Debian
Wheezy laptop for around a year now. (I'm using the Debian backports
3.12 kernel.) When I first moved to bcache, I noticed that certain
operations -- interacting with Git repositories and building LaTeX
documents, for instance -- became much snappier. I'm using a feeble
little 32GB SSD that came with the laptop to cache a 1TB drive and I'm
even using writethrough caching (more out of paranoia about the
quality of my cheap little SSD than anything else), but it makes a
difference.
Since then, it has been quietly humming along and I've stopped paying
attention to it. And that's the beauty of a good tool like this: I
can stop paying attention to it. I've enjoyed a year of better I/O
and, other than in the initial setup, I haven't paid anything in
maintenance burden: no instability, no hiccups, no unexplained hangs.
So for my part as an end user just trying to get a little edge out of
my laptop hardware, thank you! I expect I'm speaking on behalf of
quite a few people when I say that you've made things better in a
subtle but significant way. :)
Cheers,
Zach
