If a data length mismatch has been detected, report the LBA and
the lengths that do not match.

The BUG_ON(handler == NULL) statement at the start of this function
guarantees that handler != NULL. Hence remove the remaining tests of
the 'handler' pointer. Detected by Coverity.

The put_page_callback patch only improves performance on single
socket systems but not on systems with multiple CPU sockets.
Since this message is confusing to SCST users, do not print a
warning if the put_page_callback patch has not been applied.

Avoid that unknown parameters cause __vdev_load_mode_pages() to
return 0 instead of -EINVAL. Detected by Coverity.

Although RHEL 6 is based on the 2.6.32 kernel, for RHEL 6.1 the
argument list for sysfs callback functions follows the style of
kernel 2.6.35.

With the RHEL 7.0 kernel ib_register_mad_agent() takes eight
arguments. With the RHEL 7.1 kernel the same function takes nine
arguments. Detect at build time how many arguments this function
takes.

Code after BUG() is unreachable both with CONFIG_BUG=y and with
CONFIG_BUG=n. Hence remove such code. Detected by smatch.

Although the non-SRQ mode needs more resources that mode has the
advantage that the end-to-end flow control mechanism is used.
From the IB spec:
C9-150.2.1: For QPs that are not associated with an SRQ, each HCA
receive queue shall generate end-to-end flow control credits. If
a QP is associated with an SRQ, the HCA receive queue shall not
generate end-to-end flow control credits.

It is annoying that some warnings are only reported in release mode.
Modify scst_debug.h such that the compiler does not report variables
that are only used in debug builds as unused.

Avoid that the compiler complains that the variable 'pad_bytes'
is not used with CONFIG_LIBCRC32C=n.

Both OFED/MLNX_OFED compat and scst define file_inode.
This causes a compilation error. Fix this by detecting
that backports are in effect.

Avoid that running the libiscsi tests causes a high number of kernel
warnings to be triggered.
