Subject: [PATCH] module: fix lost error code from codetag_load_module()
Date: Mon, 24 Aug 2026 09:47:36 +0800	[thread overview]
Message-ID: <20260824014736.35026-1-hao.ge@linux.dev> (raw)

If codetag_load_module() fails, err is never set and load_module()
returns 0 after the module has been torn down.

Fixes: 044d2aee6c57 ("alloc_tag: handle module codetag load errors as module load failures")
Reported-by: Sashiko <sashiko-bot@kernel.org>
Cc: stable@vger.kernel.org
