mainline inclusion
from mainline-v5.9-rc1
commit de3f32e1
category: bugfix
bugzilla: 34611
CVE: NA

-------------------------------------------------

There are at least two notes in the oom section.  The 3% discount for root
processes is gone since d46078b2 ("mm, oom: remove 3% bonus for
CAP_SYS_ADMIN processes").

Likewise children of the selected oom victim are not sacrificed since
bbbe4802 ("mm, oom: remove 'prefer children over parent' heuristic")

Drop both of them.
