Yeah Chris Mason (and another) left Oracle for Fusion-IO in 2012 and
then shifted from there to Facebook in late 2013.  Jens Axboe (the
kernel block layer maintainer) also moved from Fusio-IO to Facebook
shortly after (early 2014).

FB run btrfs on a bunch of their infrastructure which helped them find
problems at scale (from memory, I don't track it any more).

All the best,
