      Description

        According to the sysinfo manpage ( https://man7.org/linux/man-pages/man2/sysinfo.2.html ) the memory and swap related entries in the struct sysinfo are given as multiples of mem_unit bytes.
        "In the above structure, sizes of the memory and swap fields are given as multiples of mem_unit bytes."

        This is considered in most parts of the OpenJDK codebase when sysinfo is used but not all; should be added where it is missing.
