Apparently the bind_alua_state functionality is being used. Hence restore
the on_alua_state_change_*() callback functions. The changes compared to
the previous implementation are:
* Only invoke the on_alua_state_change_*() callback functions if the state
of a local target port group is being modified.
* Report information about ALUA callback activity with PRINT_INFO() instead
of TRACE_MGMT_DBG().
This patch reverts commit 29548a4ad7 ("scst: Remove the
on_alua_state_change_*() callback functions").

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.
