From 703e5f708360b1400ff269a14c6837c42ef3365e Mon Sep 17 00:00:00 2001 From: Shigeru Yoshida Date: Sun, 3 Sep 2023 02:07:08 +0900 Subject: kcm: Destroy mutex in kcm_exit_net() [ Upstream commit 6ad40b36cd3b04209e2d6c89d252c873d8082a59 ] kcm_exit_net() should call mutex_destroy() on knet->mutex. This is especially needed if CONFIG_DEBUG_MUTEXES is enabled.
