    Subject[Patch 4/6] per task delay accounting taskstats interface: fix drop listener only on socket close
    From
    Date
    Remove listeners from per-cpu listener lists only if they've closed the
    socket (resulting in an ECONNREFUSED failure of genetlink unicast).
    For other errors returned by genlmsg_unicast like -EAGAIN which results
    from the receiver's buffer having insufficient space, userspace gets an
    ENOBUF warning and the kernel can continue.
