    Subject[patch 065/164] md/linear: avoid possible oops and array stop
    2.6.33-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: NeilBrown <neilb@suse.de>

    commit ef2f80ff7325b2c1888ff02ead28957b5840bf51 upstream.

    Since commit ef286f6fa673cd7fb367e1b145069d8dbfcc6081
    it has been important that each personality clears
    ->private in the ->stop() function, or sets it to a
    attribute group to be removed.
    linear.c doesn't. This can sometimes lead to an oops,
    though it doesn't always.

    Suitable for 2.6.33-stable and 2.6.34.
