From 57e67900d4c7949ad646a5f43a8ca5180170d2a0 Mon Sep 17 00:00:00 2001 From: Pranith Kumar Date: Wed, 3 Sep 2014 10:31:16 -0400 Subject: [PATCH] memfd_test: Make it work on 32-bit systems This test currently fails on 32-bit systems since we use u64 type to pass the flags to fcntl. This commit changes this to use 'unsigned int' type for flags to fcntl making it work on 32-bit systems.
