Subject: [QUESTION] jbd2: How identify what kind of metadata is in t_buffers

Is there any way to identify to what kind of metadata a specific
t_buffer is related?

On the source code it simply says that it is for metadata (in commit
phase 2b) but there is no sign of which kind of metadata these
t_buffers are storing.

Thank you.
