kmem_cache_destroy() can handle NULL pointer correctly, so there is no need
to check NULL pointer before calling kmem_cache_destroy().
For kernel versions before v4.3 there is a backport of
kmem_cache_destroy() that checks for a null pointer.
This patch fixes the following checkpatch warnings:
WARNING:NEEDLESS_IF: kmem_cache_destroy(NULL) is safe and this check
is probably not required
The legacy API wrappers in include/linux/pci-dma-compat.h should go away as
they create unnecessary midlayering for include/linux/dma-mapping.h API.
Instead use dma-mapping.h API directly.
This patch fixes build for linux kernel v5.18.
Instead of using the SCp.ptr field to track whether or not a command is
in flight, use the sp->type field to track this information. sp->type
must be set for proper operation of the qla2xxx driver. See e.g. the
switch (sp->type) statement in qla2x00_ct_entry().
Port the commit 8cc7b18f ("qla2x00t-32gbit: Stop using the SCSI pointer")
to the old qlogic driver.
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:
($ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
@@
identifier S, member, array;
type T1, T2;

struct S {

This patch fixes a bug by changing SAM_STAT_CHECK_CONDITION << 1 into
SAM_STAT_CHECK_CONDITION in the SCSI result code.

Use the proper error codes when reporting a BSG error. The DID_* codes are
the codes that are shifted left 16 bits while the DRIVER_* codes must be
shifted left 24 bits.

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

A few examples of how to run the regression tests against a distro kernel:

pr_warning() has been removed from kernel v5.5. Hence use pr_warn() instead
of pr_warning().

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.
