But these devices may also have requeued\nrequests, leaving their requests stuck from not being kicked and causing\nthe removal process of the device to hang.\n\nscsi_run_host_queues() needs to run against more devices than the macro\nshost_for_each_device() allows. Instead of using the too limiting\nscsi_device_get() state checks, only ignore devices in SDEV_DEL state or\nwhen unable to acquire a reference. Attempt to run the queues for all\nother devices when scsi_run_host_queues() is called.","state":0,"publishedAt":"2026-07-19T14:56:20.172+00:00","modifiedAt":"2026-10-19T20:18:02.511+00:00","affected":[{"ecosystem":"Vendor
