Subject: [PATCH] lib/crypto: nh: Restore dependency of arch code on !KMSAN
Date: Sun, 4 Jan 2026 21:36:52 -0800 [thread overview]
Message-ID: <20260105053652.1708299-1-ebiggers@kernel.org> (raw)
Since the architecture-specific implementations of NH initialize memory
in assembly code, they aren't compatible with KMSAN as-is.
Fixes: 382de740759a ("lib/crypto: nh: Add NH library")
Signed-off-by: Eric Biggers <ebiggers@kernel.org>
