[dm-devel] [dm-5.19 PATCH 00/21] dm: changes staged for 5.19

[Mike Snitzer]

Hi,

This patchset reflects what I've staged in linux-dm.git's "dm-5.19"
branch (also staged in "for-next" for linux-next):
https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-5.19

It build's on jens/for-5.19/block branch (which is based on v5.18-rc3)

I can still make changes or add Reviewed-by:s, etc. So please feel
free to review.

Jens, I'd appreciate it if you could pickup the first patch:
"block: change exported IO accounting interface from gendisk to bdev"
(still not in love with that subject but...)

Thanks,
Mike
