Subject: [PATCH 07/11] bcache: Fix a flush/fua performance bug
Date: Mon, 23 Sep 2013 23:17:32 -0700 [thread overview]
Message-ID: <1380003456-19938-8-git-send-email-kmo@daterainc.com> (raw)
In-Reply-To: <1380003456-19938-1-git-send-email-kmo@daterainc.com>
bch_journal_meta() was missing the flush to make the journal write
actually go down (instead of waiting up to journal_delay_ms)...
Whoops
