Hi
Not really needed in a changelog text :)
This is backport of patches d208b89401e0 ("dm: fix mempool NULL pointer race when completing IO") and 9f6dc6337610 ("dm: interlock pending dm_io and dm_wait_for_bios_completion") for the kernel 5.10.
Can you just make these 2 different patches?
The bugs fixed by these patches can cause random crashing when reloading dm table, so it is eligible for stable backport.
This patch is different from the upstream patches because the code diverged significantly.
This change is _VERY_ different. I would need acks from the maintainers of this code before I could accept this, along with a much more detailed description of why the original commits will not work here as well.
Same for the other backports.
thanks,
