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.

There is no way to know --- and it might not even be metadata if
data=journal mode in ext4 is enabled.

What are you trying to do?
