Sequence number (4 bytes) Signed integer used to reorder data logged on SMP machines. Wraparound must be taken into account, although it is unlikely. Caller address (8 bytes) Return address to the caller. Pointer to mem (8 bytes) Pointer to target memory area. Can be NULL, but not all such calls might be recorded. In case of KMEMTRACE_EVENT_ALLOC events, the next fields follow: Requested bytes (8 bytes) Total number of requested bytes, unsigned, must not be zero.
