  mm: memcontrol: fix rcu unbalance in get_non_dying_memcg_end() (2026-04-30 06:13:20 -0700)

----------------------------------------------------------------
20 hotfixes.  All are for MM (and for MMish maintainers).  9 are cc:stable
and the remainder are for post-7.0 issues or aren't deemed suitable for
backporting.

There's a 2 patch DAMON series from SeongJae Park which address races
which could lead to use-after-free errors.  And a 3 patch DAMON series
which avoids the possibility of presenting stale parameter values to
users.
