Subject: [PATCH net-next 04/12] mptcp: pm: only fill id_avail_bitmap for in-kernel pm
Date: Thu, 13 Mar 2025 11:20:53 +0100	[thread overview]
Message-ID: <20250313-net-next-mptcp-pm-ops-intro-v1-4-f4e4a88efc50@kernel.org> (raw)
In-Reply-To: <20250313-net-next-mptcp-pm-ops-intro-v1-0-f4e4a88efc50@kernel.org>

From: Geliang Tang <tanggeliang@kylinos.cn>

id_avail_bitmap of struct mptcp_pm_data is currently only used by the
in-kernel PM, so this patch moves its initialization operation under
the "if (pm_type == MPTCP_PM_TYPE_KERNEL)" condition.
