BluefoxicyI don't understand why bcache couldn't operate on normal partitions without a superblock15:09
BluefoxicyIt'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 device15:10
Bluefoxicythen, 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 drop15:11
BluefoxicyYou'd need a way for bcache to identify that a filesystem has changed since last mount, though, if you did that.  heh.15:13
