In May 2010 we saw the long awaited release of Linux 2.6.34, which includes a large XFS update. The most important features appearing in 2.6.34 was the new inode and quota flushing code, which leads to much better I/O patterns for metadata-intensive workloads. Additionally support for synchronous NFS exports has been improved to give much better performance, and performance for the fsync, fdatasync and sync system calls has been improved slightly. A bug when resizing extremely busy filesystems has been fixed, which required extensive modification to the data structure used for looking up the per-allocation group data. Last but not least there was a steady flow of minor bug fixes and cleanups, leading to the following diffstat from 2.6.33 to 2.6.34: 86 files changed, 3209 insertions(+), 3178 deletions(-) Meanwhile active development aimed at 2.6.35 merge progressed. The major feature for this window is the merge of the delayed logging code, which adds a new logging mode that dramatically reduces the bandwidth required for log I/O. See the documentation [1] for details. Testers for this new code are welcome. In userland xfsprogs saw the long awaited 3.1.2 release, which can be considered a bug fix release for xfs_repair, xfs_fsr and mkfs.xfs. After the release a few more fixes were merged into the development tree. The xfstests package saw various new tests, including many tests to exercise the quota code, and a few fixes to existing tests.
