The workqueue maintainer wants to remove the create*_workqueue() macros
because these macros always set the WQ_MEM_RECLAIM flag and because these
only support literal workqueue names. Hence this patch that replaces the
create*_workqueue() invocations with the definition of this macro. The
WQ_MEM_RECLAIM flag has been retained because I think that flag is necessary
for workqueues created by storage drivers.
Support for the following driver core changes in the Linux kernel v6.11:
- d69d80484598 ("driver core: have match() callback in struct bus_type
take a const *")
Support for the following scsi layer changes in the Linux kernel v6.10:
- 5b7dfbeff92a ("scsi: core: Add a dma_alignment field to the host and
host template")
This patch fixes the installation process for Linux kernels where the
default value of INSTALL_MOD_DIR differs from `extra`.
For instance, it unbreaks `make rpm` against Fedora's kernels, where
INSTALL_MOD_DIR is set to `updates`.
1. Correct a typo, changing `make release` to `make 2release`.
2. Add information about package-related targets to the help section.
3. Remove `dev_handler` directory during the uninstall process.
4. Eliminate the non-existent `tgt` target from the PHONY targets.
5. Introduce SCST_MOD_DIR and SCST_DH_MOD_DIR as helper variables.
The previous series of patches introduced the use of a const pointer to
scsi_host_template. However, scsi_host_alloc() uses a non-const pointer
prior to kernel version 6.4, causing the build to throw the following
error:
passing argument 1 of ‘scsi_host_alloc’ discards ‘const’
qualifier from pointer target type
Hence, cast away the constness to resolve the error.
The previous commit removed support for building with clang. Restore support
for building with clang without breaking cross-compilation support.

Since not all kernel header files are compatible with -Wextra, remove -Wextra.
To enable -Wextra, build SCST with W=1.

Simplify the scst_local driver by always using thread context for passing
commands to SCST.

$(KBUILD_EXTRA_SYMBOLS) is not only used at compile time but also at link
time. Move the $(KBUILD_EXTRA_SYMBOLS) definitions such that it is
available both at compile time and at link time.

While $(src) is always defined, $(KBUILD_EXTMOD) is only defined when
building code as an external module.

When using SG_IO it is easy to submit data buffers that do not match the
alignment requirements of vdisk_blockio. Make the submitter copy buffers
that are not aligned. See also the blk_rq_map_user() call in the Linux
kernel source file drivers/scsi/sg.c.

Copying Module.symvers is the oldest supported method for building external
kernel modules that depend on another external kernel module. Since support
for that method will be removed from Linux kernel v5.5, use
KBUILD_EXTRA_SYMBOLS instead to specify the external symbols SCST kernel
modules depend on. Support for KBUILD_EXTRA_SYMBOLS was introduced in
upstream kernel v2.6.26 so this patch drops support for kernels before
v2.6.26.

This patch adds support for kernel module namespaces. This patch is essential
when using SCST in combination with kernel version v5.4 or later.

Move the build_mode file from the top level into the scst directory. Write
build mode defines into scst/include/build_mode.h and include that file
directly or indirectly in all source files that depend on these #defines.
This approach has the advantage that "make clean" does no longer has to
be run when switching between build modes because the kernel build system
recognizes build_mode.h as a dependency and triggers a rebuild of all
source files that directly or indirectly include the build_mode.h header
file.
