Hey all,
In testing Linus' HEAD today I found another[1] regression in the block merge.
This time I see a crash on my hikey960 board shortly after booting

I bisected the issue down to "block: split bio_kmalloc from bio_alloc_bioset":
Hey all,
After updating to Linus' HEAD today I found my db845c board wouldn't
boot to android with the error below.
I was able to bisect the boot regression down to "block: add a
