    Sorry. Missed that. It was in patch 7. Any reason why this feature is
    split across 7 patches? Might be better to combine patches 1, 2, and 7
    as it contains the infrastructure type code for _OST. Something to

    There is no functional change with this patch set in the sense that _OST
    doesn't get evaluated on platforms that don't support _OST, however
    there is run-time change on all architectures with patches 3, 4, and 5.
    There are couple of new kfree() calls introduced. Something to take a
