Subject: [PATCH 0/2] mm/damon/sysfs: fix commit test damon_ctx [de]allocation
Date: Fri, 3 Oct 2025 13:14:53 -0700 [thread overview]
Message-ID: <20251003201455.41448-1-sj@kernel.org> (raw)
DAMON sysfs interface dynamically allocates and uses a damon_ctx object
for testing if given inputs for online DAMON parameters update is valid.
The object is being used without an allocation failure check, and leaked
when the test succeeds. Fix the two bugs.
