One-element arrays (and multi-element arrays being treated as dynamically sized) are deprecated[1] and are being replaced with flexible array members in support of the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy(), correctly instrument array indexing with UBSAN_BOUNDS, and to globally enable -fstrict-flex-arrays=3. Replace one-element arrays with flexible-array member in struct mvumi_msg_frame, struct mvumi_rsp_frame, and struct mvumi_hs_header, adjusting the explicit sizing calculations at the same time. This results in no functional differences in binary output. An explicit add is now folded into the size calculation: │ mov 0x1070(%r14),%eax │ - add $0x4,%eax │ - movabs $0xfffffffdc,%rbx │ + movabs $0xfffffffe0,%rbx │ add %rax,%rbx [1] https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays Cc: "James E.J.

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.
