The line in /lib/modules/4.19.0-18-amd64/build/Makefile on Debian 10 with
the path to the header files is as follows:
MAKEARGS := -C /usr/src/linux-headers-4.19.0-18-common O=/usr/src/linux-headers-4.19.0-18-amd64
while on Debian 11 the contenst of /lib/modules/5.10.0-8-amd64/build/Makefile
is as follows:
include /usr/src/linux-headers-5.10.0-8-common/Makefile
Add support for extracting the header file directory path from the Debian
10 Makefile.
Fixes: https://github.com/bvanassche/scst/issues/52
Decide which SCSI header file to include based on a compile time check instead
of trying to derive that choice from the UEK kernel version.

Since block_shift is unsigned, it can never be negative. See also commit
1e95312e49 ("Reenable block_shift calculation for tapes").

Apparently the UEK 8 FC patches have been ported to UEK 7. Make fcst build
against the latest UEK7 and UEK 8 kernels. This patch breaks compatibility
with older UEK 7 5.4.17 kernels.

r9586+r9587 added support for UEK 8 but broke support for UEK 7. Since as
far as I know no compile-time constants are available in UEK that allow to
tell the difference between the UEK 7 and UEK 8 5.4.17 kernels, extract the
UEK release number from the name of the directory with the kernel build
infrastructure.

The scsi_done() function is new in kernel v5.16. Backport it to older
kernel versions.

Instead of making vdev_open_fd() check the dev_active flag, let the callers
of this function check that flag. This patch does not change the behavior of
the scst_vdisk driver.

scst_vdisk: Restore support for adding a block device with non-existent filename
This patch is a fix for commit df4c250b8d ("scst_vdisk: Port to Linux
kernel v5.11").
See also upstream commit 7fe1e79b59ba ("configfs: implement the .read_iter
and .write_iter methods"; v5.14).

This patch fixes the build against UEK kernel 5.4.17-2136.300.7.el8uek and
breaks the build for older 5.4.17 UEK kernels, e.g.
5.4.17-2102.200.13.el8uek.

scst_cm_update_dev() calls
- scst_cm_dev_unregister(dev, false)
- scst_block_dev()
- scst_cm_get_lun()
- scst_cm_send_init_inquiry()
Due to commit 3e64094b ("scst_sysfs: Do not suspend I/O for LUN management")
scst_cm_dev_unregister() and scst_cm_get_lun() can be performed safely
without suspending SCSI command processing.
scst_block_dev() and scst_cm_send_init_inquiry() doesn't need SCST
to be suspended since scst_cm_dev_register(), which similarly calls
them, doesn't need to.
