Subject[PATCH v4 00/14] liblockdep fixes for 5.9-rc1
Date
Hi Linus,

Please consider applying these patches for liblockdep, or alternatively
pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux.git tags/liblockdep-fixes-040820

The patches fix up compilation and functionality of liblockdep on 5.8,
they were tested using liblockdep's internal testsuite.

I was unable to get the x86 folks to pull these fixes for the past few
months:

- https://lkml.org/lkml/2020/2/17/1089
- https://lkml.org/lkml/2020/4/18/817
- https://lkml.org/lkml/2020/6/22/1262

Which is why this pull request ends up going straight to you.
