Smatch and Clang both complain that LOGIN_TEMPLATE_SIZE is more than
sizeof(ha->plogi_els_payld.fl_csp).
Smatch warning:
drivers/scsi/qla2xxx/qla_iocb.c:3075 qla24xx_els_dcmd2_iocb()
warn: '&ha->plogi_els_payld.fl_csp' sometimes too small '16' size = 112
Clang warning:
include/linux/fortify-string.h:592:4: error: call to
'__read_overflow2_field' declared with 'warning' attribute: detected
read beyond size of field (2nd parameter); maybe use struct_group()?
[-Werror,-Wattribute-warning]
__read_overflow2_field(q_size_field, size);
When I was reading this code I assumed the "- 4" meant that we were
skipping the last 4 bytes but actually it turned out that we are
skipping the first four bytes.
I have re-written it remove the magic numbers, be more clear and
silence the static checker warnings.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
