    sys/kern             kern_malloc.c 
    share/man/man9       Makefile 
    sys/conf             NOTES files options 
  Added files:
    share/man/man9       redzone.9 
    sys/vm               redzone.c redzone.h 
  Log:
  Add buffer corruption protection (RedZone) for kernel's malloc(9).
  It detects both: buffer underflows and buffer overflows bugs at runtime
  (on free(9) and realloc(9)) and prints backtraces from where memory was
  allocated and from where it was freed.
