Subject: mm/damon/core: initialize ->esz_bp from damos_quota_init_priv()
Date: Fri, 3 May 2024 11:03:09 -0700
Patch series "mm/damon: misc fixes and improvements".
Add miscelleneous and non-urgent fixes and improvements for DAMON code,
selftests, and documents.
This patch (of 10):
damos_quota_init_priv() function should initialize all private fields of
struct damos_quota. However, it is not initializing ->esz_bp field. This
could result in use of uninitialized variable from
damon_feed_loop_next_input() function. There is no such issue at the
moment because every caller of the function is passing damos_quota object
that already having the field zero value. But we cannot guarantee the
future, and the function is not doing what it is promising. A bug is a
bug. This fix is for preventing possible future issues.
