Hi folks,

The following mass of patches is my current patch queue I have
pending for the 3.12 cycle. There are 4 main pieces in this:

1. kernel/user libxfs rework
        This is the first 34 patches of the series, and they have
        the single aim of removing all the differences between the
        shared userspace and kernel code. There are several new
        header files created for shared user/kernel definitions to
        remove all the __KERNEL__ sections from our header files.
        The result is about 1500 lines of code in headers files are
        no longer needlessly shared with userspace.

        Similarly, the C code itself is split up in such a ways that
        kernel only functionality is separated from the shared code.
        For example, all the readdir code is moved to
        xfs_dir2_readdir.c, and all the attribute listing code is
        moved to xfs_attr_list.c This means that the files shared
        with userpace are now mostly identical (except for
        #includes) and don't have big diffs when kernel-only code
        was cut out of the userspace versions. The only remaining
        significant differences are in xfs_rtalloc.c (needs
        splitting into kernel only/shared versions) and the generic
        btree code (different tracing in userspace).

2. Log space reservation rework from Jeff Liu
        Rebasing on the above work, and now takes into account the
        log stripe unit when determining the maximum transaction
        reservation size. This will warning if a filesystem config
        is mounted where the log may actually be physically too
        small because old mkfs programs didn't take into account the
        log stripe unit when calculating the minimum size.

3. CIL commit optimisation patchset
        This is a split up version of the RFC patch that has had a
        lot more testing and now doesn't randomly assert fail.

4. Directory entry file type support
        This adds a single byte field into the directory entries
        that indicate the type of inode that the dirent points to.
        This brings XFS up to the same functionality as ext4 and
        btrfs, and enables us to support whiteout dirents for union
        mounts. It also greatly speeds use directory traversals as
        we no longer need to stat every inode to find out which ones
        are subdirectories that need to be walked.

I have one remaining bit of functionality to complete for 3.12, and
that is a new extent swap implementation for CRC enabled
filesystems. I hope to have that complete and ready for review
within a week.

This series will be followed by an xfsprogs patchset that
complements this series to be applied to the crc-dev branch. It
makes all the same changes and gives us the most similar
code base between kernel and userspace that we've had in many, many
years....

Comments, flames, testing and crazy emails all welcome.

Cheers,

Dave.
