kindly ignore this patch, the feature now is implemented without adding any _new_ ioctl or _new_ parameters.

btrfs-progs has to read fs info from the kernel to read the latest info instead of reading it from the disks, which generally is a stale info after certain critical operation. getting used_bytes parameter will help to fix btrfs filesystem show --kernel to show the current info of the fs Signed-off-by: Anand Jain <anand.jain@oracle.com> --- ioctl.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
