ext4 according to wikipedia is:
The ext4 or fourth extended filesystem is a journaling file system for Linux, developed as the successor to ext3.
And is was created…
…as a series of backward compatible extensions to ext3 meant to extend storage limits and add other performance improvements. However, other Linux kernel developers opposed accepting extensions to ext3 for stability reasons, and proposed to fork the source code of ext3, rename it as ext4, and do all the development there, without affecting the current ext3 users. This proposal was accepted, and on 28 June 2006, Theodore Ts’o, the ext3 maintainer, announced the new plan of development for ext4.
