Subject: [PATCH 2/2] ksmbd: smbd: fix connection dropped issue
Date: Wed, 18 May 2022 06:46:08 +0900	[thread overview]
Message-ID: <20220517214608.283538-2-hyc.lee@gmail.com> (raw)
In-Reply-To: <20220517214608.283538-1-hyc.lee@gmail.com>

When there are bursty connection requests,
RDMA connection event handler is deferred and
Negotiation requests are received even if
connection status is NEW.

To handle it, set the status to CONNECTED
if Negotiation requests are received.
