May saw the release of Linux 3.4, including a decent sized XFS update. Remarkable XFS features in Linux 3.4 include moving over all metadata updates to use transactions, the addition of a work queue for the low-level allocator code to avoid stack overflows due to extreme stack use in the Linux VM/VFS call chain, better xattr operation tracing, fixes for a long-standing but hard to hit deadlock when using the XFS real time subvolume, and big improvements in disk quota scalability. The final diffstat for XFS in Linux 3.4 is: 61 files changed, 1692 insertions(+), 2356 deletions(-) In the meantime the merge window for Linux 3.5 opened, and another large update has been merged into Linus' tree. Interesting changes in Linux 3.5-rc1 include improved error handling on buffer write failures, a drastic reduction of locking overhead when doing high-IOPS direct I/O, removal of the old xfsbufd daemon in favor of writing most run-time metadata from the xfsaild daemon, deferral of CIL pushes to decouple user space metadata I/O from log writeback, and last but not least the addition of the SEEK_DATA/SEEK_HOLE lseek arguments that allow user space programs to deal with sparse files efficiently. Traffic on the mailing list has been a bit quiet in May, mostly focusing on a wide range of bug fixes, but little new features. On the user space side xfs_repair saw a few bug fixes posted to the list that didn't make it to the repository yet, while xfstests saw it's usual amount of minor bug fixes. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
