Subject: jbd: Annotate transaction start also for journal_restart()
X-Git-Tag: v2.6.32-rc1~647^2~3
X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=3adae9da0b35d2ca908039f42a1e90395c335181;p=net-next-2.6.git

jbd: Annotate transaction start also for journal_restart()

lockdep annotation for a transaction start has been at the end of
journal_start(). But a transaction is also started from journal_restart(). Move
the lockdep annotation to start_this_handle() which covers both cases.
