Message-ID: <20231218153454.8090-35-linkinjeon@xxxxxxxxxx>
From: Hyunchul Lee <hyc.lee@xxxxxxxxx>
[ Upstream commit ddbdc861e37c168cf2fb8a7b7477f5d18b4daf76 ]
SMB2_READ/SMB2_WRITE request has to be granted the number
of rw credits, the pages the request wants to transfer
/ the maximum pages which can be registered with one
MR to read and write a file.
And allocate enough RDMA resources for the maximum
number of rw credits allowed by ksmbd.
