use taskq_del_barrier() instead of taskq_barrier() when flushing work prompted by jcs@ reporting a protection fault trap in drm_mode_rmfb_work_fn() while playing a youtube video in firefox on a kaby lake machine. He later saw the same trace on tiger lake. The arguments to drm_mode_rmfb_work_fn() are on the stack in drm_mode_rmfb() with flush_work() called before return. taskq_barrier() is only a barrier for running not queued tasks. I suspect the linux functions expect any previously queued work to complete not just any currently running work. I'm not sure if the difference matters in practice. |

| message |
Remove another unused DMA allocation from iwx(4). This driver does not need to allocate a DMA segment for the Tx scheduler. Instead this driver uses the scheduler byte count array which is allocated per Tx ring. Remove sc->sched_dma and related code inherited from iwm(4). Patch by zxystd from OpenIntelWireless. |
