Summary of changes between versions 3.5 and 3.6
-----------------------------------------------
- Made the command processing path slightly faster by removing two atomic
instructions from the command processing path.
- Added support for the READ and WRITE DYN RUNTIME ATTR commands and also
for SERVICE ACTION IN(12).
- An infinite loop in the code that sets CHECK CONDITION has been fixed.
- A deadlock has been fixed in the code for assigning a device handler to a
vdisk.
- Support for adding a vdisk_blockio device with a non-existent filename has
been restored.
- The async mode of vdisk_fileio has been made compatible with filesystems that
use the iomap code, e.g. XFS.
- A "INFO: rcu_sched self-detected stall" issue has been fixed.
- Support in the copy manager for auto_cm_assignment=0 has been fixed.
- Standards-compliance of the copy manager has been improved. Designators with
a length above 20 bytes are now rejected instead of being accepted.
- The copy manager no longer suspends activity when adding a LUN.
- A bug has been fixed in the vdisk resync_size functionality.
- The tape device handler now sets 'block_shift' correctly.
- Improved the code for building a Debian package (dpkg).
- scst_local: the SCSI host number is now available in sysfs.
- scst-isert: support for RDMA_CV_EVENT_ADDR_CHANGE has been added.
- scst-isert: a hang in iscsi_release() has been fixed.
- The top-level Makefile has been modified such that the qla2x00t-32gbit driver
is built by default instead of the qla2x00t driver. The qla2x00t driver can
be selected by passing QLA_32GBIT=no as argument to make.
- qla2x00t-32gbit driver: updated from Linux kernel version v5.10 to v5.15.
- scstadmin: the -force option is now passed to removeGroup().
- scstadmin: improved performance of the scstadmin function make_path().
The kernel versions supported by this release are:
* Kernel.org kernel versions v3.10..v5.15.
* Debian / Ubuntu kernels based on upstream kernel versions v3.10..v5.15.
* RHEL / CentOS 7.x and 8.0..8.5 kernels.
