Overall no objection from me. I've always pushed to have the tests be

it already takes some work, so this isn't introducing an undue
hardship.

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
ASOP. See the log below.
I bisected the issue down to "block: split bio_kmalloc from bio_alloc_bioset":
https://git.kernel.org/pub/scm/li
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
disk_uevent helper":
