From e0a8144b8c32031d37ff849fc07e6c5646e61198 Mon Sep 17 00:00:00 2001 From: "John L. Hammond" Date: Wed, 30 Mar 2016 19:48:52 -0400 Subject: [PATCH] staging/lustre/llite: use vui prefix for struct vvp_io members Rename members of struct vvp_io to used to start with vui_ rather than cui_. Rename several instances of struct vvp_io * from cio to vio. Signed-off-by: John L.
