AUTHORS

The ext2fs kernel implementation is derived from code written, or modified, by Godmar Back using the UFS CSRG sources for CMU Mach.

John Dyson did the initial port to FreeBSD . Aditya Sarawgi merged important parts of the allocation code from a clean-room NetBSD implementation. Zheng Liu and Fedor Upurov implemented the read and write support respectively for ext4 filesystems. The FreeBSD community has contributed a huge amount of modifications.

The initial version of this manual page was written by Craig Rodrigues <Mt rodrigc@FreeBSD.org>.
