- * @brief Define an embedded stack memory region
- *
- * Used for stacks embedded within other data structures. Use is highly
- * discouraged but in some cases necessary. For memory protection scenarios,
- * it is very important that any RAM preceding this member not be writable
- * by threads else a stack overflow will lead to silent corruption. In other
- * words, the containing data structure should live in RAM owned by the kernel.
- *
- * A user thread can only be started with a stack defined in this way if
- * the thread starting it is in supervisor mode.
- *
- * @deprecated This is now deprecated, as stacks defined in this way are not
- *             usable from user mode. Use K_KERNEL_STACK_MEMBER.
- *
- * @param sym Thread stack symbol name
- * @param size Size of the stack memory region
