Subject: [PATCH 0/2] mm/damon/{reclaim,lru_sort}: fix commit_inputs infinite hang
Date: Mon,  3 Aug 2026 06:46:43 -0700	[thread overview]
Message-ID: <20260803134646.16640-1-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.
