From f696bf6d64b195b83ca1bdb7cd33c999c9dcf514 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 18 Jul 2018 09:25:14 -0700 Subject: RDMA: Constify the argument of the work request conversion functions When posting a send work request, the work request that is posted is not modified by any of the RDMA drivers. Make this explicit by constifying most ib_send_wr pointers in RDMA transport drivers.
