Hello!
What's the reasoning for exposing bcache devices as being
non-rotational? Currently, it fools btrfs into using ssd allocation
scheme on the underlying harddisks which isn't really what I expected
to get. So I used a udev rule to change this:
ACTION=="add|change", KERNEL=="bcache*", ATTR{queue/rotational}="1"
Wouldn't it make more sense to set this to the same value as the
underlying backing device by default?
Because in reality, the bcache is still what the backing device is: A
rotational medium. A cache doesn't make this non-rotational.
Thoughts?
