Since all callers (process_{read,write}) set id->dir, no need to
pass 'dir' again.

I applied the patch and cleanup of rtrs-srv.h can be done later.

Thanks! I suppose below

So decouple it from rtrs-srv.h and hide everything that not-needed to be
exported to separate header file.

means move 'struct rtrs_srv_op' to rtrs.h, which seems not appropriate to me
because both client and server include the header. Pls correct me if I
am wrong.

Since process_{read,write} prints direction info if ctx->ops.rdma_ev
fails, how
about remove the 'dir' info from rnbd_srv_rdma_ev? Then we  don't need to
include rtrs-srv.h.

Thoughts?

I like the idea. Please post a formal patch based on leon's
https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/log/?h=wip/leon-for-next

I squashed this hunk into original patch.

Thanks

Thx!
