qnx6_checkroot() had been using weirdly spelled initializer - it needed to initialize 3-element arrays of char and it used NUL-padded 3-character string literals (i.e. 4-element initializers, with completely pointless zeroes at the end). That had been spotted by gcc-15[*]; prior to that gcc quietly dropped the 4th element of initializers. However, none of that had been needed in the first place - all this array is used for is checking that the first directory entry in root directory is "." and the second - "..". The check had been expressed as a loop, using that match_root[] array. Since there is no chance that we ever want to extend that list of entries, the entire thing is much too fancy for its own good; what we need is just a couple of explicit memcmp() and that's it.

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 reStructuredText 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.
