XFS
XFS is a high-performance journaling file system created by SGI (formerly Silicon Graphics Inc.) for their Irix Unix implementation. In May 2001, SGI released XFS under an open source licence.It comes by default with the 2.5.xx and 2.6.xx versions of the Linux kernel, but wasn't available to the 2.4.xx kernel, except as a patch, until version 2.4.25 when it was judged stable enough to be merged into the main development tree by Marcelo Tosatti, maintainer of the 2.4 branch.
