From ed288d74a9e5d9ff869350906ad35eb231c55388 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 18 Jul 2018 09:25:31 -0700 Subject: [PATCH] net/xprtrdma: Simplify ib_post_(send|recv|srq_recv)() calls Instead of declaring and passing a dummy 'bad_wr' pointer, pass NULL as third argument to ib_post_(send|recv|srq_recv)().
