The quilt patch titled
     Subject: mm/damon/lru_sort: use damon_kdamond_pid()

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/damon/lru_sort: use damon_kdamond_pid()
Date: Thu, 15 Jan 2026 07:20:43 -0800

DAMON_LRU_SORT directly uses damon_ctx->kdamond field with manual
synchronization using damon_ctx->kdamond_lock, to get the pid of the
kdamond.  Use a new dedicated function for the purpose, namely
damon_kdamond_pid(), since that doesn't require manual and error-prone
synchronization.
