From d3a94048c912e18e99a091d5ea2d0a1178152d6f Mon Sep 17 00:00:00 2001 From: Alexander Block Date: Mon, 25 Jun 2012 15:36:12 -0600 Subject: Btrfs: use _IOR for BTRFS_IOC_SUBVOL_GETFLAGS We used the wrong ioctl macro for the getflags ioctl before. As we don't have the set/getflags ioctls in the user space ioctl.h at the moment, it's safe to fix it now.
