Please refer to v1 ([1]) and background ([2]) for more details.
As Sasha suggested in [3], revert commit 9e07f4e24379 ("zram: close udev startup race condition as default groups") first, and then apply the original patch set.
- patch 5: fix the issue of zram that the original commit (9e07f4e24379) wants to fix - patch 6: fix the issue of virtio-blk ([2]) - patch 3/4: I have not occured with these two issues in real world. Put here just for completeness.
This patch set is for 4.19, though it shall be backported to 4.4/4.9/4.14/4.19. Send this patch set out first for more feedbacks.
I have only tested the issue of virtio-blk though.
