Hi Christoph ,
Yes, it's always false now. As blk_mq_commit_rqs is a general function
for all commits now, I keep the from_schedule for commits where
from_schedule maybe true in future. We can remove from_schedule now
and add it back when from_schedule is indeed needed. Both way is
acceptable for me. Please let me know which way do you prefer and I
will send a new version if needed.
Thanks.
