Subject: [PATCH 11/12] ext4 balloc: use io_error label


------------------------------------------------------
Subject: ext2 balloc: use io_error label
From: Hugh Dickins <hugh@...itas.com>

ext2_new_blocks has a nice io_error label for setting -EIO, so goto that in
the one place that doesn't already use it.

------------------------------------------------------
Fix it in ext4_new_blocks.
