+Internally, KASAN tracks memory state separately for each memory granule, which
 is either 8 or 16 aligned bytes depending on KASAN mode. Each number in the
 memory state section of the report shows the state of one of the memory
 granules that surround the accessed address.

+For generic KASAN, the size of each memory granule is 8. The state of each

+encoding for each shadow byte: 00 means that all 8 bytes of the corresponding
 memory region are accessible; number N (1 <= N <= 7) means that the first N
 bytes are accessible, and other (8 - N) bytes are not; any negative value
 indicates that the entire 8-byte word is inaccessible. KASAN uses different
 negative values to distinguish between different kinds of inaccessible memory
 like redzones or freed memory (see mm/kasan/kasan.h).

+Note that KASAN bug titles (like ``slab-out-of-bounds`` or ``use-after-free``)
