From c4b8e635f525441b9cb0bab428b527858d977e8f Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 5 Feb 2008 10:55:26 -0500 Subject: [PATCH] jbd2: Fix reference counting on the journal commit block's buffer head With journal checksum patch we added asynchronous commits of journal commit headers, and accidentally dropped taking a reference on the buffer head. (Before the change, sync_dirty_buffer did the get_bh(). The associative put_bh is done by journal_wait_on_commit_record().)
