Module Name:    src
Committed By:   maxv
Date:           Sun Dec 16 21:03:35 UTC 2018

Modified Files:
        src/sys/kern: subr_pool.c
        src/sys/sys: pool.h

Log Message:
Add support for detecting use-after-frees in KASAN. We poison each freed
buffer, any subsequent read or write will be detected as illegal.

 * Add POOL_CHECK_MAGIC, which is disabled under KASAN, because the same
   detection is done in a better way.

 * Register the size+redzone in the pool structure, to reduce the overhead.

 * Fix the CTOR/DTOR check in KLEAK, the fields are never NULL.
