Journaling block device Journaling block device JBD, or journaling block device, is a generic block device journaling layer in the Linux kernel written by Stephen C. Tweedie from Red Hat. The Journaling Block Device (JBD) provides a filesystem-independent interface for filesystem journaling. ext3, ext4 and OCFS2 are known to use JBD.

An atomic handle is basically a collection of all the low-level changes that occur during a single high-level atomic update to the file system.
