eb34335f2f scst: Suppress a warning in scst_cm_update_dev() 
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.

Use a two digit revision number instead of a single digit revision number to
fix a lintian warning. Exclude .gitignore files from the source archive.
Copy the debhelper major version number into debian/compat instead of
hardcoding the compatibility level because the highest compatibility level
supported by Ubuntu 16.04 is 9 and because compatibility level 9 is considered
deprecated by Ubuntu 20.04.

Since the soft link scstadmin/scstadmin is under source control, do not
remove it while removing build artefacts. See also commit b3435fbdda
("debian/rules: Also clean the scstadmin/scstadmin soft link").

1b3d5b60eb scst: Rework the mechanism for suspending activity 
Use a percpu_ref instead of one atomic counter per CPU. This patch
eliminates two atomic instructions from the command processing path.
This patch decreases performance for the following configurations
because the backported version of percpu_ref uses a single global
counter:
* RHEL 6.x / CentOS 6.x and before (maintenance ended on 2020-11-30).
* Upstream kernel version v3.10 and before.
