34  * Memory management macros to aid in developing code that can
35  * be compiled for both user and kernel.
36  *
37  * Set the AREA parameter to a short text string that is a hint
38  * about the subsystem calling the function. example: "smbrdr"
39  *
40  * Do not mix usage of these macros with malloc/free functions.
41  * It will not work.
42  *
43  * All library code shared between user and kernel must use
44  * these functions instead of malloc/free/kmem_*.

46  * Quick Summary
47  * MEM_MALLOC - allocate memory
48  * MEM_ZALLOC - allocate and zero memory
49  * MEM_STRDUP - string copy
50  * MEM_REALLOC - reallocate memory
51  * MEM_FREE -  free memory
