    Subject[GIT PULL] barrier/flush write revamp for 2.6.37-rc1
    Hi Linus,

    Another topic branch, this one has the barrier rewrite for 2.6.37-rc1.
    It's been in for-next for a long time, no surprises seen yet (except for
    the xen-blkfront, but that was broken before as well).

    This greatly simplifies the barrier support and semantics, as the
    diffstat confirms.

    Please pull.
