Subject: [PATCH v2 bpf-next 1/4] bpf: lsm: Remove hook to bpf_task_storage_free
Date: Tue, 12 Nov 2024 00:36:57 -0800 [thread overview]
Message-ID: <20241112083700.356299-2-song@kernel.org> (raw)
In-Reply-To: <20241112083700.356299-1-song@kernel.org>
free_task() already calls bpf_task_storage_free(). It is not necessary
to call bpf_task_storage_free() again on security_task_free(). Remove
the hook to bpf_task_storage_free.
