    Subject[PATCH 3.16 086/294] i40e: Initialize 64-bit statistics TX ring seqcount
    3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

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

    From: Florian Fainelli <f.fainelli@gmail.com>

    commit 7d6d067790289e4f61f59fa60550ca5918aa25bd upstream.

    On 32-bit hosts and with CONFIG_DEBUG_LOCK_ALLOC we should be seeing a
    lockdep splat indicating this seqcount is not correctly initialized, fix
    that.
