From: Christoph Hellwig <hch@infradead.org> To: xfs@oss.sgi.com, linux-fsdevel@vger.kernel.org, linux-kernel@vger.kernel.org Subject: XFS status update for January 2011 Date: Sun, 13 Feb 2011 13:42:19 -0500 [thread overview] Message-ID: <20110213184219.GA22792@infradead.org> (raw) On the 4th of January we saw the release of Linux 2.6.37, which contains a large XFS update: 67 files changed, 1424 insertions(+), 1524 deletions(-) User visible changes are the new XFS_IOC_ZERO_RANGE ioctl which allows to convert already allocated space into unwritten extents that return zeros on a read, and support for 32-bit wide project IDs. The other large item are various changes to improve metadata scalability even further, by changes to the the buffer cache, inode lookup and other parts of the filesystem driver. After that the XFS development tree for 2.6.38 was merged into mainline, with an even larger set of changes. Notable items include support for the FITRIM ioctl to discard unused space on SSDs and thinly provisioned storage systems, a buffer LRU scheme to improve hit rates for metadata, an overhaul of the log subsystem locking, dramatically improving scalability in that area, and much smarter handling of preallocations, especially for files closed and reopened frequently, e.g. by the NFS server. User space development has been very quite, with just a few fixes committed to the xfstests repository, although various additional patches for xfsprogs and xfstests that haven't been committed yet were discussed on the mailing list.
