We're hitting this warning in ext4 on the linux-4.3 nfs server running over

Svcrdma was incorrectly allocating fastreg MRs and page lists using
RPCSVC_MAXPAGES, which can exceed the device capabilities. So limit
the depth to the minimum of RPCSVC_MAXPAGES and xprt->sc_frmr_pg_list_len.

Moving the amso1100 driver to staging now requires a guard on the
INFINIBAND subsytem in order to prevent the driver from being built
without infiniband enabled. This will lead to a broken build.

Currently the sg tablesize, which dictates fast register page list
depth to use, does not take into account the limits of the rdma device.
So adjust it once we discover the device fastreg max depth limit. Also
adjust the max_sectors based on the resulting sg tablesize.

Ideally, the post contains a chain of all 4 registrations and the
rdma_read (and an opportunistic good scsi response).
Just to be clear: This example is for IB only, correct? IW would
require rkeys with REMOTE_WRITE and 4 read wrs.
My assumption

isert_reg_read_frmr(). Otherwise is uses the lkey map service
isert_map_lkey() for RDMA WRITEs.
isert_reg_read_frmr() will create a linked list of WR triplets of the
form: INV->FRWR->READ. The number of these triplets is dependent on
the devices fast reg page list length limit.

Use the device's max_fast_reg_page_list_len attr to size the SQ
and FRMR pool.

Use the device's max_sge_rd capability to compute the target's read sge
depth. Save both the read and write max_sge values in the isert_conn
struct, and use these when creating RDMA_WRITE/READ work requests.

Currently the sg tablesize, which dictates fast register page list
depth to use, does not take into account the limits of the rdma device.
So adjust it once we discover the device fastreg max depth limit. Also
adjust the max_sectors based on the resulting sg tablesize.
