From bffe690708c8b4fdb8f0bff8ff22b347fc6c709a Mon Sep 17 00:00:00 2001 From: Andrey Konovalov Date: Tue, 22 Dec 2020 12:02:59 -0800 Subject: kasan: open-code kasan_unpoison_slab There's the external annotation kasan_unpoison_slab() that is currently defined as static inline and uses kasan_unpoison_range(). Open-code this function in mempool.c. Otherwise with an upcoming change this function will result in an unnecessary function call.
