Can this information become relevant for another update step?

I find this commit reference interesting somehow.
How do you think about the commit 786ae133e07f2a6b352a0efad16b555ee45a2898
("lib: fix test_hmm.c reference after free" from 2020-06-26)
and the commit 1f9c4bb986d978a5e39153b39a71c9d098b65c5c ("mm/memremap_pages:
convert to 'struct range'" from 2020-09-23) for your update suggestion?
Regards,
Markus
