Deduplication of kasan_enabled() checks which are already used by callers. * Altered functions: check_page_allocation Delete the check because callers have it already in __wrappers in include/linux/kasan.h: __kasan_kfree_large __kasan_mempool_poison_pages __kasan_mempool_poison_object kasan_populate_vmalloc, kasan_release_vmalloc Add __wrappers in include/linux/kasan.h. They are called externally in mm/vmalloc.c. __kasan_unpoison_vmalloc, __kasan_poison_vmalloc Delete checks because there're already kasan_enabled() checks in respective __wrappers in include/linux/kasan.h. release_free_meta -- Delete the check because the higher caller path has it already. See the stack trace: __kasan_slab_free -- has the check already __kasan_mempool_poison_object -- has the check already poison_slab_object kasan_save_free_info release_free_meta kasan_enabled() -- Delete here Link: https://lkml.kernel.org/r/20251009155403.1379150-3-snovitoll@gmail.com Signed-off-by: Sabyrzhan Tasbolatov <snovitoll@gmail.com> Reviewed-by: Andrey Konovalov <andreyknvl@gmail.com> Cc: Alexander Potapenko <glider@google.com> Cc: Andrey Ryabinin <ryabinin.a.a@gmail.com> Cc: Baoquan He <bhe@redhat.com> Cc: Christophe Leroy <christophe.leroy@csgroup.eu> Cc: Dmitriy Vyukov <dvyukov@google.com> Cc: "Ritesh Harjani (IBM)" <ritesh.list@gmail.com> Cc: Vincenzo Frascino <vincenzo.frascino@arm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
