git-ocfs

    The OCFS2 filesystem.  OK by me, although I'm not sure it's had enough
    review.

Every time I come up with a complaint about ocfs2, the Oracle guys manage to shoot me down. I think it's OK to merge.


sparsemem

    OK by me for a merge.  Need to poke arch maintainers first, check that
    they've looked at it sufficiently closely.

seems sane, though there are some whitespace niggles that should be cleaned up


rapidio-*

    Will merge.

send through netdev, as is proper


dlm-*.patch: Red Hat distributed lock manager

    Hard.  Right now it seems that no in-kernel projects will use this and
    only one out-of-kernel project will use it.  Shelve the problem until
    after Kernel Summit, where some light may be shed.

    Opinions are sought...

I hate to say it, since its my own employer, but I agree: wait for in-kernel users, at the very least.


connector.patch

    Nice idea IMO, but there are still questions around the
    implementation.  More dialogue needed ;)

connector-add-a-fork-connector.patch

    OK, but needs connector.

I don't like connector


inotify

    There are still concerns about the userspace API and internal
    implementation details.  More slogging needed.

We should ask hpa what he needs for kernel.org. Ideally kernel.org probably wants <something> that facilitates listening to <something> for a list of files being changed. That would greatly speed up the robots, and possibly rsync-like activities too.


pcmcia-*.patch

    Makes the pcmcia layer generate hotplug events and deprecates cardmgr.
    Will merge.

Testing? The goal behind the patch is certainly good, but I worry about exposure.


cachefs

    This is a ton of code which knows rather a lot about pagecache
    internals.  It allows the AFS client to cache file contents on a local
    blockdev.

    I don't think it's a justified addition for only AFS and I'd prefer to
    see it proven for NFS as well.

    Issues around add-page-becoming-writable-notification.patch need to
    be resolved.

cachefs-for-nfs

    A recent addition.  Needs review from NFS developers and considerably
    more testing.

    These things aren't looking likely for 2.6.13.

If I could vote more than once, I would! I really like cachefs, and have been pushing for its inclusion for a while.


kexec and kdump

    I guess we should merge these.

    I'm still concerned that the various device shutdown problems will
    mean that the success rate for crashing kernels is not high enough for
    kdump to be considered a success.  In which case in six months time we'll
    hear rumours about vendors shipping wholly different crashdump
    implementations, which would be quite bad.

    But I think this has gone as far as it can go in -mm, so it's a bit of
    a punt.

I'm not particularly pleased with these, and indeed vendors ARE shipping other crashdump methods.


reiser4

    Merge it, I guess.

    The patches still contain all the reiser4-specific namespace
    enhancements, only it is disabled, so it is effectively dead code.  Maybe
    we should ask that it actually be removed?

The plugin stuff is crap. This is not a filesystem but a filesystem + new layer. IMO considered in that light, it duplicates functionality elsewhere.


v9fs

    I'm not sure that this has a sufficiently high
    usefulness-to-maintenance-cost ratio.

agreed (though I think 9P is neat)


      It has been said that a userspace NFS server can be used to get
      full NFS server functionality with FUSE.  I think the half-assed kernel
      implementation should be done away with.

"It has been said" -- its true. A userspace NFS server can do 100% of userspace FS functionality.
