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.

Instead of only checking the mlnx-ofed-kernel-dkms package name, also check
the mlnx-ofed-kernel-modules package name.

When building against Oracle Linux + MOFED the build fails unless if
DTrace is disabled. Hence disable DTrace for the isert-scst module if
MOFED is detected.

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.

This patch avoids that the build_mode file is read when applying the

Move the $(SCST_INC_DIR) definitions from the out-of-tree sections into
the in-kernel sections. Since SCST is now distributed as a single tar
archive, only support in-tree builds with $(SCST_INC_DIR) and $(SCST_DIR).

This patch is necessary to make SCST work with Linux kernel v5.1 and
does not change any functionality. See also upstream commit 736706bee329
("get rid of legacy 'get_ds()' function").

conn->sock is set by the TCP/IP transport but not by the iSER transport.
Hence check the conn->sock pointer from common code before dereferencing it.

[PATCH] kbuild: external module support
From: Sam Ravnborg <sam@ravnborg.org>
Based on initial patch from Andreas Gruenbacher there is now better support
for building external modules with kbuild.
The preferred syntax is now:
make -C $KERNELSRC M=$PWD
but the old syntax:
make -C $KERNELSRC SUBDIRS=$PWD modules
will remain supported.

Since RHEL 5 and kernel versions before 2.6.26 rely on procfs support,
this patch removes support for RHEL 5.x and also for kernel versions
before 2.6.26.

Zero-copy TCP/IP support is deprecated since a while and is no longer
supported for recent kernels. Hence remove it and also all references
to zero-copy TCP/IP support.
