DragonFlyBSD Lands New EXT2/3/4 File-System Driver

While DragonFlyBSD has its own, original HAMMER2 file-system, for those needing to access data from EXT2/EXT3/EXT4 file-systems, there is a brand new "ext2fs" driver implementation for this BSD operating system.

DragonFlyBSD has long offered an EXT2 file-system driver (that also handles EXT3 and EXT4) while hitting their Git tree this week is a new version. The new sys/vfs/ext2fs driver, which will ultimately replace their existing sys/gnu/vfs/ext2fs driver is based on a port from FreeBSD code. As such, this driver is BSD licensed rather than GPL. But besides the more liberal license to jive with the BSD world, this new driver has various feature/functionality improvements over the prior version. However, there are some known bugs so for the time being both file-system drivers will co-exist.

More details on this new non-GPL EXT2 file-system driver via this commit with the work performed by Tomohiro Kusumi.
