@ -6,7 +6,7 @@ Kernel Objects
A kernel object can be one of three classes of data:
* A core kernel object, such as a semaphore, thread, pipe, etc.
* A thread stack, which is an array of :c:type:`struct _k_thread_stack_element`
* A thread stack, which is an array of :c:type:`struct z_thread_stack_element`
and declared with :c:macro:`K_THREAD_STACK_DEFINE()`
* A device driver instance (struct device) that belongs to one of a defined
set of subsystems
