Subject: kasan: remove __kasan_save_free_info wrapper
Date: Thu, 9 Oct 2025 20:54:02 +0500

Patch series "kasan: cleanups for kasan_enabled() checks".

This patch series is the continuation of [1] the previous discussion
related to the KASAN internal refactoring.

Here we remove kasan_enabled() checks which are duplicated by higher
callers.  These checks deduplication are also related to the separate
patch series [2].


This patch (of 2):

We don't need a kasan_enabled() check in kasan_save_free_info() at all. 
Both the higher level paths (kasan_slab_free and
kasan_mempool_poison_object) already contain this check.  Therefore,
remove the __wrapper.
