From 986dbb586fdacbc1e530131b8f075fc7c7d4c506 Mon Sep 17 00:00:00 2001 From: Andreas Dilger Date: Wed, 23 Nov 2016 17:59:51 -0500 Subject: [PATCH] staging: lustre: ldlm: change "int" to proper enum type Fix users of flags that were using "int" instead of named enum. Rename some "flags" variables to distinguish between different flags.
