Message-ID: <20201218200858.kEUQy%akpm@linux-foundation.org> (raw)


The patch titled
     Subject: kasan: don't use read-only static keys
has been removed from the -mm tree.  Its filename was
     kasan-add-and-integrate-kasan-boot-parameters-fix.patch

This patch was dropped because it was folded into kasan-add-and-integrate-kasan-boot-parameters.patch

------------------------------------------------------
From: Andrey Konovalov <andreyknvl@google.com>
Subject: kasan: don't use read-only static keys

__ro_after_init static keys are incompatible with usage in loadable kernel
modules and cause crashes.  Don't use those, use normal static keys.
