Subject: [RFC PATCH 0/2] mm/damon/{reclaim,lru_sort}: fix commit_inputs infinite hang
Date: Sun, 2 Aug 2026 11:54:26 -0700 [thread overview]
Message-ID: <20260802185430.9940-1-sj@kernel.org> (raw)
Writing 'Y' to commit_inputs parameters of DAMON_RECLAIM and
DAMON_LRU_SORT before the modules were ever turned on causes infinite
hang. Fix those.
The issue was discovered [1] by Sashiko.
