Ming Lei a0ba41317c scsi: core: Run queue in case of I/O resource contention failure ... [ Upstream commit 3f0dcfbcd2 ] I/O requests may be held in scheduler queue because of resource contention. The starvation scenario was handled properly in the regular completion path but we failed to account for it during I/O submission. This lead to the hang captured below. Make sure we run the queue when resource contention is encountered in the submission path.
