Igor Konopko 751a0cc0cd nvme-pci: fix surprise removal ... When a PCIe NVMe device is not present, nvme_dev_remove_admin() calls blk_cleanup_queue() on the admin queue, which frees the hctx for that queue. Moments later, on the same path nvme_kill_queues() calls blk_mq_unquiesce_queue() on admin queue and tries to access hctx of it, which leads to following OOPS: Oops: 0000 [#1] SMP PTI RIP: 0010:sbitmap_any_bit_set+0xb/0x40 Call Trace: blk_mq_run_hw_queue+0xd5/0x150 blk_mq_run_hw_queues+0x3a/0x50 nvme_kill_queues+0x26/0x50 nvme_remove_namespaces+0xb2/0xc0 nvme_remove+0x60/0x140 pci_device_remove+0x3b/0xb0 Fixes: cb4bfda62a ("nvme-pci: fix hot removal during error handling") Signed-off-by: Igor Konopko <igor.j.konopko@intel.com> Reviewed-by: Keith Busch <keith.busch@intel.com> Signed-off-by: Christoph Hellwig <hch@lst.de>		2018-11-27 18:12:26 +01:00
