    Subject[079/111] Btrfs: apply updated fallocate i_size fix
    2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

    From: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

    commit 23b5c50945f2294add0137799400329c0ebba290 upstream.

    This version of the i_size fix for fallocate makes sure we only update
    the i_size when the current fallocate is really operating outside of
    i_size.
