19  * KERN_SLABALLOC.C - Kernel SLAB memory allocator
77  * This function will set a hook function, which will be invoked when a memory
78  * block is allocated from heap memory.
89  * This function will set a hook function, which will be invoked when a memory
90  * block is released to heap memory.
114  * In a kernel implementation all this memory will be physical so
116  * memory.  The upside is that overhead is bounded... this is the *worst*
120  * are required, only a critical section.  When one cpu frees memory
155  *    + ability to allocate arbitrarily large chunks of memory
468  * This function will allocate a block from system heap memory.
471  * - If there is no nbytes sized memory valid in system,
474  * @param size the size of memory to be allocated
476  * @return the allocated memory

551          * No chunks are available but nfree said we had some memory, so  in rt_malloc()
552          * it must be available in the never-before-used-memory area  in rt_malloc()
671  * This function will change the size of previously allocated memory block.
673  * @param ptr the previously allocated memory block
674  * @param size the new size of memory block
676  * @return the allocated memory
721          * Allocate memory for the new request size.  Note that zoneindex has  in rt_realloc()
740  * that are size bytes of memory each and returns a pointer to the allocated
741  * memory.
743  * The allocated memory is filled with bytes of value zero.
748  * @return pointer to allocated memory / NULL pointer if there is an error
757     /* zero the memory */  in rt_calloc()
766  * This function will release the previous allocated memory block by rt_malloc.
767  * The released memory block is taken back to system heap.
769  * @param ptr the address of memory which will be released
