Hi,

I noticed that bfq doesn't appear in the I/O scheduler list on
4.19-rc3.  It seems that blkcg_policy_register() at the beginning of
bfq_init() returns -ENOSPC, hence the probe aborts silently.

Is this already addressed?

Haven't heard about this one before. What kernel did you last use that
worked?

IIRC, 4.18 worked fine.  Let me see whether I have a backup...
