3.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kent Overstreet <kmo@daterainc.com>
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
