This feature also allowed adding support for discard support at transaction commit time using the discard mount option. While the implementation of discards in XFS is state of the art it should be considered mostly a technology preview until various efficiency issue in the block layer discard support are sorted out. Another important feature visible to users is that XFS now supports using external logs even when using volatile write caches, although the implementation is not fully optimized yet, the rest of the changes consists of the usual pile of bug fixes and a relatively small set of cleanups. After the release of Linux 3.0 the merge window for Linux 3.1 also fell mostly into July. The XFS merge for 3.1 included further speedups for the AIL code, and a huge amount of cleanups. On the userspace side the biggest item was the merge of the libxfs resync with the Linux 2.6.39 kernel code. In addition to that xfsprogs saw small xfs_repair updates, xfstests saw various fixes to fsx, and various build system fixes were commit to all userspace repositories. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
