e9c9cc8b6a Makefile: Introduce the 'make rpm-dkms' 
For convenience, there is a lack of opportunity to build
the SCST dkms and scstadmin packages in a one command.

Introduce the 'make rpm-dkms' command that in similar way to 'make rpm'
builds SCST dkms rpm packages and then builds scstadmin rpm packages.

33b872d055 vdisk_fileio, async mode: Switch from kvec to bvec 
fileio_exec_async() for fileio devices with o_direct flag triggers
the following Linux direct_io datapath:
- fileio_exec_async()      -- ... --> iomap_dio_bio_actor()
- iomap_dio_bio_actor()    -- ... --> bio_iov_iter_get_pages()
- bio_iov_iter_get_pages() -- ... --> iov_iter_get_pages()
- iov_iter_get_pages() returns -EFAULT

iov_iter_get_pages() only handles iovec and bvec iterators.
Its kvec hanlding always return -EFAULT.

We cannot use iovec because calling iov_iter_init() from
the kernel context initializes iov_iter as ITER_KVEC.

Thus, use bvecs for fileio async direct IO.

32fd54f3ef fcst: Fix the Debian 10 build 
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.

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.
