Subject: XFS status update for March 2012
Date: Tuesday 8th May 2012 15:35:26 UTC (over 4 years ago)
March saw the release of Linux 3.3, which saw an XFS update slightly smaller than usual, and consisting largely of code removal and cleanups, with the only user visible change being the removal of the old logging code, and thus the "nodelaylog" mount option. This is reflected in a diffstat with more than twice as many deletions as additions: 45 files changed, 954 insertions(+), 2182 deletions(-) After that Linux 3.4 merge window opened, and a big XFS updates was merged into mainline, again removing a lot more code than adding it. The highlight are quota changes to make in-memory quota caching a lot faster and more scalable, as well as changes to log all metadata updates on a live XFS filesystem, thus finishing the consolidation of all metadata I/O code pathes to just after many years of hard work. Development for the Linux 3.5 merge window also were in full steam, including a series to kill the xfsbufd daemon in favour of on-stack delayed buffer writeback lists. On the user space side we finally saw the long awaited xfsprogs 3.1.8 and xfsdump 3.1.0 releases. The new xfsprogs release features a larger number of repair fixes and speedups, as well as smaller updates to the other tools. All users are recommended to upgrade to this version. Major updates in xfsdump 3.1.0 is support for dumping multiple I/O streams in parallel, a new dump format to support all 32 bits of the inode generation number, removal of support for the old SGI_XFSDUMP_SKIP_FILE extended attribute, as well as various smaller fixes. Development of xfstests included at its normal pace, with a few new test cases for xfsdump, as well as various fixes for existing test cases and the addition of a new "dangerous" group to skip tests that potentially crash the system if an too old kernel is used.
