Subject: [RFC PATCH ipsec-next 1/6] xfrm: propagate extack to all netlink doit handlers
Date: Thu, 11 Nov 2021 13:02:42 +0100	[thread overview]
Message-ID: <450482993e7930dbae1ab06a93ec6115224ab8d9.1636450303.git.sd@queasysnail.net> (raw)
In-Reply-To: <cover.1636450303.git.sd@queasysnail.net>

xfrm_user_rcv_msg() already handles extack, we just need to pass it down.
