XFS File-System Speeded-Up, Cleaned-Up Last Month

A status report of the XFS file-system for January 2012 has been released. This report outlines some of then notable improvements made to this popular enterprise-grade Linux file-system for the Linux 3.2 and 3.3 kernels.

XFS in the Linux 3.2 kernel brought large speed-ups for removing certain files, speed-ups and live-lock fixes for sync while doing heavy I/O, and large internal clean-ups of the inode block map handling.

As far as what the forthcoming Linux 3.3 file-system will have in store for the XFS file-system, there is the removal of deprecated pre-delaylog logging code, various quota clean-ups, a shrink of the inode, and great simplification of the file write path. There's also a variety of bug-fixes and code clean-ups.

The user-space program side of XFS has also seen major fixes and speed-ups. The xfsdump utility has also seen long-standing bug-fixes.

The 2012 January XFS status report can be read on the kernel mailing list.
