------------------------------------------------------ From: Jianglei Nie niejianglei2021@163.com Subject: mm/damon/reclaim: fix potential memory leak in damon_reclaim_init() Date: Thu, 14 Jul 2022 14:37:46 +0800

damon_reclaim_init() allocates a memory chunk for ctx with damon_new_ctx(). When damon_select_ops() fails, ctx is not released, which will lead to a memory leak.

We should release the ctx with damon_destroy_ctx() when damon_select_ops() fails to fix the memory leak.
