Subject: damon/sysfs: fix possible memleak on damon_sysfs_add_target
Date: Mon, 26 Sep 2022 16:06:11 +0000
When damon_sysfs_add_target couldn't find proper task, New allocated damon_target structure isn't registered yet, So, it's impossible to free new allocated one by damon_sysfs_destroy_targets.
By calling damon_add_target as soon as allocating new target, Fix this possible memory leak.
