    Subject[PATCH 3.11 033/198] Target/iser: Wait for proper cleanup before unloading
    Date
    3.11.10.13 -stable review patch.  If anyone has any objections, please let me know.

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

    From: Sagi Grimberg <sagig@mellanox.com>

    commit f5ebec9629cf78eeeea4b8258882a9f439ab2404 upstream.

    disconnected_handler works are scheduled on system_wq.
    When attempting to unload, first make sure all works
    have cleaned up.
