From f64705b8715a090cd5526a2c082eeb199a51e8b2 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Mon, 19 Mar 2018 11:30:43 -0600 Subject: [PATCH] RDMA/ocrdma: Fix structure layout for ocrdma_alloc_pd The udata's for alloc_pd cannot contain u64s due to alignment constraints. Switch the two never-used u64's to arrays of u32 to reduce the required struct alignment to 4 bytes. These reserved fields are totally unnecessary, never written and never read.
