From: Alexander Block Date: Mon, 25 Jun 2012 21:36:12 +0000 (-0600) Subject: Btrfs: use _IOR for BTRFS_IOC_SUBVOL_GETFLAGS X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d3a94048c912e18e99a091d5ea2d0a1178152d6f;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git 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.
