aa43bb2c0f smb: smbdirect: remove unused SMBDIRECT_USE_INLINE_C_FILES logic 
We always build as standalone module (or as part of the core kernel).

This also removes unused elements from struct smbdirect_socket
and unused exports.

00ac2a4fe0 smb: smbdirect: remove unused smbdirect_connection_mr_io_recovery_work() 
This would actually never be used as we only move to
SMBDIRECT_MR_ERROR when we directly call
smbdirect_socket_schedule_cleanup().

Doing an ib_dereg_mr/ib_alloc_mr dance on
working connection is not needed and
it's also pointless on a broken connection
as we don't reuse any ib_pd.

81a7a3a0fa smb: smbdirect: introduce smbdirect_netdev_rdma_capable_mode_type() 
This is basically a copy of ksmbd_rdma_capable_netdev() in the
server, but this also prints a message when a device is renamed.

The differences are:
- It uses rdma_for_each_port() instead of implementing the
  same logic again.
- It returns RDMA_NODE_{UNSPECIFIED,IB_CA,RNIC} values instead of bool

50bdab9ae4 smb: server: make use of smbdirect.ko 
This means we no longer inline the common smbdirect
.c files and use the exported functions from the
module instead.

Note the connection specific logging is still
redirect to ksmbd.ko functions via
smbdirect_socket_set_logging().

We still don't use real socket layer,
but we're very close...

2eff5e51f9 smb: server: make use of smbdirect_socket_{listen,accept}() 
We no longer need the custom rdma listener.

The code logic is very similar to transport_tcp.c now
using a kernel thread that loops over smbdirect_socket_accept().

This is the first step in the direction of using IPPROTO_SMBDIRECT
sockets in future.

da20536c50 smb: server: let smbdirect_map_sges_from_iter() truncate the message boundary 
smbdirect_map_sges_from_iter() already handles the case that only
a limited number of sges are available. Its return value
is data_length and the remaining bytes in the iter are
remaining_data_length.

This is now much easier and will allow us to share
more code with the client soon.

73489efdda smb: server: make use of smbdirect_connection_recvmsg() 
This is basically the same logic, it just operates on iov_iter_kvec()
instead of a raw buffer pointer. This allows us to use common
code between client and server.

We keep returning -EINTR instead of -ERESTARTSYS if
wait_event_interruptible() fails. I don't if this is
required, but changing it is a task for another patch.

8d55169a57 smb: server: make use of smbdirect_connection_recv_io_refill[_work]() 
This is basically a copy of smb_direct_post_recv_credits(), but
there are several improvements compared to the existing function:

1. We calculate the number of missing posted buffers by getting the
   difference between recv_io.credits.target and recv_io.posted.count.

   Instead of the difference between recv_io.credits.target
   and recv_io.credits.count, because recv_io.credits.count is
   only updated once a message is send to the peer.

   It was not really a problem before, because we have
   a fixed number smbdirect_recv_io buffers, so the
   loop terminated when smbdirect_connection_get_recv_io()
   returns NULL.

   But using recv_io.posted.count makes it easier to
   understand.

2. In order to tell the peer about the newly posted buffer
   and grant the credits, we only trigger the send immediate
   when we're not granting only the last possible credit.

   This is mostly a difference relative to the servers
   smb_direct_post_recv_credits() implementation,
   which should avoid useless ping pong messages.

ab8e9249e7 smb: server: make use of smbdirect_connection_qp_event_handler() 
This is a copy of smb_direct_qpair_handler()...

It will allow more code to be moved to common functions
soon.

8688d7a8c7 smb: server: make use of smbdirect_map_sges_from_iter() 
It will make it easier to move stuff into common code when
both client and server use smbdirect_map_sges_from_iter().

07aec3a151 smb: server: make use of smbdirect_connection_{create,destroy}_mem_pools() 
This were based on smb_direct_{create,destroy}_pools() in the server.

The main logical differences are the following:

We now don't use smbdirect_connection_get_recv_io() on cleanup,
instead it uses list_for_each_entry_safe()...

We don't generate warnings if smbdirect_recv_io payload
is copied into userspace buffers. This doesn't happen
in the server anyway.

And it uses list_add_tail() just to let me feel
better when looking at the code...

bb1d5c49d6 smb: server: make use of smbdirect_connection_send_io_done() 
This also wakes up send_io.pending.dec_wait_queue, which
is currently always empty in the server, but that might
change in future. And we also don't spam the logs on IB_WC_WR_FLUSH_ERR.

8ecb32ada1 smb: server: make use of smbdirect_connection_{alloc,free}_send_io() 
These are basically copies of smb_direct_{alloc,free}_sendmsg() just
a bit simpler and with the gfp_mask mask abstracted.

For now we still use KSMBD_DEFAULT_GFP, which includes
__GFP_RETRY_MAYFAIL.

The only difference is that we use ib_dma_unmap_page() for all sges,
this simplifies the logic and doesn't matter as
ib_dma_unmap_single() and ib_dma_unmap_page() both operate
on dma_addr_t and dma_unmap_single_attrs() is just an
alias for dma_unmap_page_attrs().
We already had such an inconsistency in the client
code where we use ib_dma_unmap_single(), while we mapped
using ib_dma_map_page().

Note smbdirect_socket_prepare_create() already calls INIT_DELAYED_WORK().

These are basically copies of {get,put}_receive_buffer() in the client.
They are very similar to {get_free,put}_recvmsg() the only logical
difference is the updating of the sc->statistics.*.

the same as smbdirect_socket_schedule_cleanup().

calling wake_up_all(&sc->mr_io.ready.wait_queue); and
wake_up_all(&sc->mr_io.cleanup.wait_queue); in addition
should not matter as it's not used on the server anyway.

6acc747906 smb: client: make use of smbdirect.ko 
This means we no longer inline the common smbdirect
.c files and use the exported functions from the
module instead.

Note the connection specific logging is still
redirect to cifs.ko functions via
smbdirect_socket_set_logging().

We still don't use real socket layer,
but we're very close...
