Re: [PATCH 6.1 214/219] mm, kmsan: fix infinite recursion due to RCU critical section

I was initially interested in backporting the commit dc904345e3 ("mm,
kmsan: fix infinite recursion due to RCU critical section") to 5.10 and
5.15. However, this commit does not apply cleanly to those versions.
Additionally, it seems this commit was intended to fix a bug introduced
by commit 5ec8e8ea8b77 ("mm/sparsemem: fix race in accessing
memory_section->usage") in 6.1, but that buggy commit may not be
problematic in 5.10 or 5.15.

Thanks,
Arnav
