Subject: [PATCH 1/3] ksmbd: reduce smb direct max read/write size
Date: Sun, 30 Jan 2022 18:34:31 +0900	[thread overview]
Message-ID: <20220130093433.8319-1-linkinjeon@kernel.org> (raw)

To support RDMA in chelsio NICs, Reduce smb direct read/write size
to about 512KB. With this change, we have checked that a single buffer
descriptor was sent from Windows client, and intel X722 was operated at
that size.
