Suppress the following warning: WARNING: CPU: 0 PID: 6998 at scst/src/scst_copy_mgr.c:2672 scst_cm_update_dev+0xdc/0x110 This warning can be triggered during unregistration of a virtual device with the following test case: 1. Change a parameter of the virtual device, e.g. the USN. 2. Delete the LUN. That triggers the following sequence: 1. vdev_del_device() 2. scst_unregister_virtual_device() 3. scst_acg_del_lun() 4. cancel the work struct associated with vdev_inq_changed_fn(). 5. visk_detach() 6. vdev_del_device() finishes. vdev_inq_changed_fn() may get called after a LUN has been unregistered from the copy manager and before device deletion finishes.

Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
QLogic target driver
Two QLogic target drivers are included in the SCST project. The driver in the qla2x00t directory is a very stable driver that supports up to 16 Gb/s adapters. It is very stable, well tested and actively used in many production setups.
There is also a newer driver that supports 32 Gb/s FC in the qla2x00t-32gbit directory. That driver has not yet reached the same maturity level as the old qla2x00t driver.
