[ 07/57] bcache: Fix a flush/fua performance bug

[Greg Kroah-Hartman]

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

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

From: Kent Overstreet <kmo@xxxxxxxxxxxxx>

commit 1394d6761b6e9e15ee7c632a6d48791188727b40 upstream.

bch_journal_meta() was missing the flush to make the journal write
actually go down (instead of waiting up to journal_delay_ms)...

Whoops
