Subject: [RFC PATCH v2 3/4] jbd2: replace jbd_debug with the new log interface
From: Chunguang Xu <brookxu@...cent.com>
In order to support jbd2 per device debugging switch, here we need to
replace jbd_debug with a new log interface. But there is a small
disadvantage here. Because the debugging switch is placed in the journal_t
object, the log before the object is initialized will be lost. However,
usually this will not have much impact on debugging.
