Ext3 users - Sep 2002 - kjournald & jbd

Hello everybody,

Could someone please explain to me what is the difference between
kjournald and jbd (precisely, what does each of them do?)

Thank you,
Alina

jbd is the journaling layer which ext3 uses.  One of the things that
the jbd layer does is to batch updates to the disk into compound
atomic transactions, and those are written to disk in the background.
kjournald is the name of the thread that the jbd code creates to
perform those background commits.

Cheers,
 Stephen
