Hello Greg!
I've seen this patch failed to apply to 4.19 and 4.14 stable trees but you've still merged (some) of the patches following this one from the same series. Honestly, I would not consider the result very trustworthy. The code involved is rather complex with subtle interactions across subsystems. So please remove also upstream commits:
ea591cd4eb27 ("bfq: Update cgroup information before merging bio") fc84e1f941b9 ("bfq: Drop pointless unlock-lock pair") 5f550ede5edf ("bfq: Remove pointless bfq_init_rq() calls") 09f871868080 ("bfq: Track whether bfq_group is still online") 4e54a2493e58 ("bfq: Get rid of __bio_blkcg() usage") 075a53b78b81 ("bfq: Make sure bfqg for which we are queueing requests is online")
from 4.14 and 4.19 stable queues. If someone will need these fixes there, he'll need to do proper backport with targetted testing etc... Thanks!
Only 2 ended up applying there, so I've dropped those two now, thanks!
