Bisect fingered the commit below.  I confirmed that reverting that
commit on top of stable-rc/linux-4.10.y gets this am335x-pepper
platform booting again.   What's rather strange is that this boot test
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.
