The definition of OBD_ALLOC_POST() needs ot be corrected so that it can be used as it it used:

#define OBD_ALLOC_POST(ptr, size, name)                                 \
                obd_memory_add(size);                                   \
                CDEBUG(D_MALLOC, name " '" #ptr "': %d at %p.\n",       \
                       (int)(size), ptr)

...

#define __OBD_MALLOC_VERBOSE(ptr, cptab, cpt, size, flags)                    \
do {                                                                          \
        (ptr) = (cptab) == NULL ?                                             \
                kmalloc(size, (flags) | __GFP_ZERO) :                         \
                cfs_cpt_malloc(cptab, cpt, size, (flags) | __GFP_ZERO);       \
        if (likely((ptr) != NULL))                                            \
                OBD_ALLOC_POST(ptr, size, "kmalloced");                       \
} while (0)
