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

This patch fixes the following Coverity complaint:
7. assignment: Assigning: usn_len = max_len. The value of usn_len is now 252.
CID 326814 (#1 of 1): Out-of-bounds access (OVERRUN)
8. overrun-buffer-arg: Overrunning array virt_dev->usn of 21 bytes by
passing it to a function which accesses it at byte offset 251 using
argument usn_len (which evaluates to 252).
Fixes: ca180efeec ("scst_vdisk: Avoid that vdisk_usn_vpd() can trigger a buffer overflow")

Use lockdep_register_key() and lockdep_unregister_key() instead of
disabling lockdep checking for certain lock objects. See also Linux
kernel commit 108c14858b9e ("locking/lockdep: Add support for dynamic
keys"; kernel version v5.1).

Remove this debug assert because it a write residual can happen, e.g. if the
expected transfer length exceeds the Data Out buffer length. This statement
was hit by the following CDB, submitted by the libiscsi regression tests:

This patch makes it possible to build the ib_srpt driver against a kernel
before v5.1 + latest MOFED.

In shutdown/reboot paths, the timer is not stopped:
qla2x00_shutdown
pci_device_shutdown
device_shutdown
kernel_restart_prepare
kernel_restart
sys_reboot
This causes lockups (on powerpc) when firmware config space access calls
are interrupted by smp_send_stop later in reboot.

This patch fixes issue with Gen7 adapter in a blade environment where one
of the ports will not be detected by driver. Firmware expects mailbox 11 to
be set or cleared by driver for newer ISP.

Commit 88263208dd23 ("scsi: qla2xxx: Complain if sp->done() is not called
from the completion path") introduced the WARN_ON_ONCE in
qla2x00_status_cont_entry(). The assumption was that there is only one
status continuations element. According to the firmware documentation it is
possible that multiple status continuations are emitted by the firmware.
