Subject: [PATCH V2] mm/damon: simplify damon_ctx check in damon_sysfs_before_terminate
Date: Thu, 8 Sep 2022 10:19:12 +0800 [thread overview]
Message-ID: <20220908021912.70481-1-xhao@linux.alibaba.com> (raw)
In damon_sysfs_before_terminate() func, it need to check whether
ctx->ops.id supports 'DAMON_OPS_VADDR' or 'DAMON_OPS_FVADDR', there we
can use damon_target_has_pid() instead.
