From d731cd3c3a8db7f179f1e52ccf9b02e1ab8227a1 Mon Sep 17 00:00:00 2001 From: Taylor R Campbell Date: Thu, 31 Mar 2022 02:45:29 +0000 Subject: [PATCH 45/49] unix(4): Convert membar_exit to membar_release. Leave an XXX comment here because I don't know what this pairs with, but (deprecated) membar_exit and (new) membar_release have identical semantics so this can't break anything. --- sys/kern/uipc_usrreq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sys/kern/uipc_usrreq.c b/sys/kern/uipc_usrreq.c index ac7cf5428d26..a51e82970868 100644 --- a/sys/kern/uipc_usrreq.c +++ b/sys/kern/uipc_usrreq.c @@ -291,7 +291,7 @@ unp_setpeerlocks(struct socket *so, struct socket *so2) lock = unp->unp_streamlock; unp->unp_streamlock = NULL; mutex_obj_hold(lock); - membar_exit(); + membar_release(); /* XXX what does this pair with? */ /* * possible race if lock is not held - see comment in * uipc_usrreq(PRU_ACCEPT).
