Subject: [PATCH bpf-next] bpf: lsm: Remove hook to bpf_task_storage_free
Date: Wed, 11 Dec 2024 23:59:56 -0800 [thread overview]
Message-ID: <20241212075956.2614894-1-song@kernel.org> (raw)
free_task() already calls bpf_task_storage_free(). It is not necessary
to call it again on security_task_free(). Remove the hook.
Signed-off-by: Song Liu <song@kernel.org>

This was initially sent in a patchset [1]. However, this patch is not
closely related to other patches in the set, so sending it alone.
