    Subject[2.6.24-rc BUGFIX] IB/srp: release transport when removing host
    When removing the ib_srp module, srp_remove_one() does not release the
    SRP transport class when it is releasing the SCSI host. This leads to
    dangling references to kfree()'d memory, and an eventual oops.

    Not sure if your Acked-by was for this one as well, so I left it off.
