[15:09] <Bluefoxicy> I don't understand why bcache couldn't operate on normal partitions without a superblock
[15:10] <Bluefoxicy> It'd just need to perform writes to the partition in the same order as the filesystem itself attempted to perform them--which should be easy, since (as far as I understand) it's between the file system driver and the block device
[15:11] <Bluefoxicy> then, if you yanked the bcache out after a power drop--even after writeback that didn't make it to the system--and mounted without bcache, you'd have exactly what would have happened in a power drop some time between the cache write and the actual power drop
[15:13] <Bluefoxicy> You'd need a way for bcache to identify that a filesystem has changed since last mount, though, if you did that.  heh.
