From 04cfa521cd6f38d7cd735ead5b7978390664042e Mon Sep 17 00:00:00 2001 From: Justus Winter Date: Mon, 25 Apr 2016 00:54:08 +0200 Subject: Avoid superfluous locking of node * libdiskfs/io-restrict-auth.c (diskfs_S_io_restrict_auth): Do not lock the associated node. No operation here needs synchronization. * libnetfs/io-restrict-auth.c (netfs_S_io_restrict_auth): Likewise. --- libnetfs/io-restrict-auth.c | 3 --- 1 file changed, 3 deletions(-) (limited to 'libnetfs/io-restrict-auth.c') diff --git a/libnetfs/io-restrict-auth.c b/libnetfs/io-restrict-auth.c index 79b7d095..89df6716 100644 --- a/libnetfs/io-restrict-auth.c +++ b/libnetfs/io-restrict-auth.c @@ -42,19 +42,16 @@ netfs_S_io_restrict_auth (struct protid *user, if (err) return err; - pthread_mutex_lock (&user->po->np->lock); refcount_ref (&user->po->refcnt); newpi = netfs_make_protid (user->po, new_user); if (newpi) { *newport = ports_get_right (newpi); - pthread_mutex_unlock (&user->po->np->lock); *newporttype = MACH_MSG_TYPE_MAKE_SEND; } else { refcount_deref (&user->po->refcnt); - pthread_mutex_unlock (&user->po->np->lock); iohelp_free_iouser (new_user); err = ENOMEM; } -- cgit v1.2.3
