From 19c38b632d4554329986021fd66bdea468cf452c Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 12 Feb 2010 19:22:24 -0800 Subject: sysfs: Pack sysfs_dirent more tightly. Placing the 16bit s_mode between a pointer and a long doesn't pack well especailly on 64bit where we wast 48 bits. So move s_mode and declare it as a unsigned short. This is the sysfs backing store after all we don't need fields extra large just in case someday we want userspace to be able to use a larger value. Acked-by: Tejun Heo Signed-off-by: Eric W.
