Subject: Re: kmemleak report after 9082e87bfbf8 ("block: remove struct bio_batch")

Hi Catalin,

I've got a few reports of this over the weekend, but it still doesn't
make much sense to me.

Could it be that kmemleak can't deal with the bio_batch logic?  I've
tried to look at the various bio and biovec number entries in
/proc/slabinfo, and while they keep changing a bit during the
system runtime there doesn't seem to be a persistent increase
even after lots of mkfs calls.

Can all of you who have reported the issue take a look at their
slabinfo files and check if you can confirm that observation?
