    Phoronix: XFS Is Becoming Leaner While Btrfs & EXT4 Gain Weight

    Red Hat's Eric Sandeen has written an interesting blog post concerning the size of popular Linux file-systems and their kernel modules. It turns out that the XFS file-system is losing lines of code, while maintaining the same feature-set and robustness, but the EXT4 and Btrfs file-systems continue to have a net increase in lines of code...

    May be we can find if there is any real improvement by a phoronix benchmark

      That's the only sentence that is needed.

        It's also noteworthy that according to the graph on the original post ext4 is only approaching half of the LOCs of xfs...

            Yeah, the fact that XFS code has been decreasing kind of proves the point. That it was complicated and not extremely well integrated with Linux, otherwise it shouldn't be possible to be consistently reducing the LOCs like that over an extended period of time. But at least it's getting better.

              XFS has always served me well. During the days EXT4 was still causing data corruption, XFS did its job.
              The only problem I had, was when I broke the hard drive's partition table. It took me a while to get a utility to recover the XFS partition. It worked, eventually.

                Given that XFS was originally ported directly from IRIX I wouldn't be surprised if there was a "compatability layer" in place to map any systemcalls that weren't present in Linux. Given that IRIX has been dead in water since 2006 the guys in SGI/XFS can over time reduce dependency on such a layer -- as they don't have to maintain codebase with IRIX XFS anymore.

                  It's not the first time forum is more informative than article.

                    I am not sure why you call it an article. This was submitted under "Latest Linux News".
