Date: Thu Nov 22 2012 - 17:29:10 EST


3.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alex Elder <elder@xxxxxxxxxxx>

(cherry picked from commit df6ad1f97342ebc4270128222e896541405eecdb)

Move init_bio_iter() and iter_bio_next() up in their source file so
the'll be defined before they're needed.
