Btrfs: hold a ref on the inode during writepages We can race with unlink and not actually be able to do our igrab in btrfs_add_ordered_extent. This will result in all sorts of problems. Instead of doing the complicated work to try and handle returning an error properly from btrfs_add_ordered_extent, just hold a ref to the inode during writepages. If we cannot grab a ref we know we're freeing this inode anyway and can just drop the dirty pages on the floor, because screw them we're going to invalidate them anyway.
