Subject: [PATCH 1/1] fault-inject: Include linux/types.h by default.

Functions should_fail_alloc_page, should_failslab, and __should_failslab
are declared irrespective of CONFIG_FAULT_INJECTION. These functions use
bool and gfp_t types, which are treated as unknown when
CONFIG_FAULT_INJECTION is disabled because the inclusion of linux/types.h
is missing.

Fixes: 6ff1cb355e62 ("[PATCH] fault-injection capabilities infrastructure")
