Subject: writeback: Fix ABI change in 3.14.10
Bug-Debian: https://bugs.debian.org/754902
Forwarded: not-needed

Commit 1c8349a17137 ("ext4: fix data integrity sync in ordered mode")
renamed test_set_page_writeback() to __test_set_page_writeback() and
added a function-macro under the old name as a wrapper.
test_set_page_writeback() was an exported function that is used by
some OOT modules including openafs.  To keep old modules working, we
need to provide a real function as well.
