Subject: [PATCH] tools: include kasan header in slabtoprate
slabtoprate fails on 5.10 kernels because of a missing kasan_reset_tag
declaration. We need to include the kasan header file.
Fixes the following error:
In file included from /virtual/main.c:12:
include/linux/slub_def.h:181:27: warning: implicit declaration of function 'kasan_reset_tag' is invalid in C99 [-Wimplicit-function-declaration]
return reciprocal_divide(kasan_reset_tag(obj) - addr,
