ovl: copy up file size as well
Copy i_size of the underlying inode to the overlay inode in ovl_copyattr(). This is in preparation for stacking I/O operations on overlay files. This patch shouldn't have any observable effect. Remove stale comment from ovl_setattr() [spotted by Vivek Goyal]. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
