From a4097fdb2f0bab0fabb69461ff58194908f91e89 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Tue, 21 Feb 2012 12:56:51 +0100 Subject: [PATCH] PR 2026/filesystem - Fix semaphore attributes Semaphores of type RTEMS_SIMPLE_BINARY_SEMAPHORE are not suitable for a mutex. Use RTEMS_BINARY_SEMAPHORE with RTEMS_INHERIT_PRIORITY instead. --- cpukit/libfs/src/rfs/rtems-rfs-mutex.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/cpukit/libfs/src/rfs/rtems-rfs-mutex.c b/cpukit/libfs/src/rfs/rtems-rfs-mutex.c index 04d700a916..f35350f653 100644 --- a/cpukit/libfs/src/rfs/rtems-rfs-mutex.c +++ b/cpukit/libfs/src/rfs/rtems-rfs-mutex.c @@ -24,15 +24,10 @@ #if __rtems__ /** * RTEMS_RFS Mutex Attributes - * - * @warning Do not configure as inherit priority.
