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.
