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.
