Bisect fingered the commit below. I confirmed that reverting that
commit on top of stable-rc/linux-4.10.y gets this am335x-pepper

is using a .cpio.gz initramfs, and not using any ext4 filesystem.

ext4: fix inline data error paths

commit eb5efbcb762aee4b454b04f7115f73ccbcf8f0ef upstream.

The write_end() function must always unlock the page and drop its ref
count, even on an error.
