Subject: [RFC PATCH v1.1 0/3] mm/damon: fix wrong behaviors in DAMOS quota goals and sysfs refresh_ms
Date: Thu, 27 Aug 2026 06:44:25 -0700	[thread overview]
Message-ID: <20260827134429.123023-1-sj@kernel.org> (raw)

DAMOS quota goals and DAMON sysfs refresh_ms file have bugs that can
produce non critical but still unexpected behaviors.  Fix the two bugs.

Patches 1 and 2 fix the bugs in DAMOS PSI goal initialization and
eligible_mem_bp online commit, respectively.  Patch 3 fixes the bug in
DAMON sysfs refresh_ms file handling.

Changes from RFC
- RFC: https://lore.kernel.org/20260827042920.93580-1-sj@kernel.org
  (Mistakenly missed RFC tag)
- Fix build error.
- Add eligible_mem_bp nid commit fix.

SJ Park (3):
  mm/damon/core: initialize damos_quota_goal->last_psi_total
  mm/damon/core: copy nid for eligible_mem_bp damos quota goal commit
  mm/damon/sysfs: set next refresh jiffies per sysfs context
