I'm one of those that used to have problems with btrfs on top of bcache.
After some corruptions, I gave up this setup.

Recently (from February, I think) I gave it another shot, and I have
had no problems since.
I use bcache in writeback mode, with very good performance. I'm
feeling btrfs very stable in this setup.

Best Regards,

Fabio Pfeifer
