Anas Nashif	0c9e280547	cleanup: include/: move misc/mutex.h to sys/mutex.h ... move misc/mutex.h to sys/mutex.h and create a shim for backward-compatibility. No functional changes to the headers. A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES. Related to #16539 Signed-off-by: Anas Nashif <anas.nashif@intel.com>	2019-06-27 22:55:49 -04:00

Andrew Boie	f0835674a3	lib: os: add sys_mutex data type ... For systems without userspace enabled, these work the same as a k_mutex. For systems with userspace, the sys_mutex may exist in user memory. It is still tracked as a kernel object, but has an underlying k_mutex that is looked up in the kernel object table. Future enhancements will optimize sys_mutex to not require syscalls for uncontended sys_mutexes, using atomic ops instead.
