May finally saw the release of Linux 2.6.39, which was a little more calm than usual for XFS, and only contains about half the amount of the changes we are used to see: 58 files changed, 1660 insertions(+), 1912 deletions(-) The most visible change is an overhaul of the XFS-internal interfaces to print kernel messages, which makes all messages from XFS look slightly different from before by always providing information about which device these messages relate to. In addition to that support for the RT subvolume, which had been broken for a while has been resurrect, the XFS buffer cache switched away from using the Linux pagecache to improve performance on metadata intensive workloads, and all but one of the XFS kernel threads have been switched to the new concurrent managed workqueue infrastructure that is present in more recent Linux 2.6 releases. In the meantime development for the release now known as Linux 3.0 went ahead full steam up to the merge of the XFS tree into Linux 3.0-rc1. News in that release contain support for vastly improved busy extent tracking, support for online discard (aka TRIM) and the usual amount of bug fixes. On the user space side the xfsprogs saw a fix for a corner case in xfs_repair, and xfstests saw a few bug fixes as well as a new test case to test btrfs-specific functionality. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
