I want to add online defrag support to ext2/3/4 just to scratch an itch. I've searched the archives and googled around, and I've come to the following conclusions: *An offline defrag tool is available but dangerous. *Some patches exist that provide preliminary support for online defrag in the ext3 driver, but interest in improving/integrating these patches is low. *An implementation of an ext* filesystem driver can work with any ext2/3/4 filesystem as long as it supports the necessary revision (GOOD_OLD_REV or DYNAMIC_REV) and feature flags set in the filesystem. Please let me know if any of my assumptions are incorrect.
