  "message": "[SCSI] target: Fix bug with task_sg chained transport_free_dev_tasks release\n\nThis patch addresses a bug in the target core release path for HW\noperation where transport_free_dev_tasks() was incorrectly being called\nfrom transport_lun_remove_cmd() while releasing a se_cmd reference and\ncalling struct target_core_fabric_ops-\u003equeue_data_in().\n\nThis would result in a OOPs with HW target mode when the release of\nse_task-\u003etask_sg[] would happen before pci_unmap_sg() can be called in\nHW target mode fabric module code.  This patch addresses the issue by\nmoving transport_free_dev_tasks() from transport_lun_remove_cmd() into\ntransport_generic_free_cmd(), and adding TRANSPORT_FREE_CMD_INTR and\ntransport_generic_free_cmd_intr() to allow se_cmd descriptor release\nto happen fromfrom within transport_processing_thread() process context\nwhen release of se_cmd is not possible from HW interrupt context.\n\nSigned-off-by: Nicholas Bellinger \u003cnab@linux-iscsi.org\u003e\nCc: stable@kernel.org\nSigned-off-by: James Bottomley \u003cjbottomley@parallels.com\u003e\n",
