Description of problem:  A recent kernel-ark change switched the symvers compression from gzip to xz, however, the /usr/sbin/weak-modules script only looks for gzip'd symvers files.


Version-Release number of selected component (if applicable): kmod-28-8.el9.x86_64


How reproducible: 100%


Steps to Reproduce:
1.  Download rpms from https://koji.fedoraproject.org/koji/buildinfo?buildID=2194617

kernel-6.4.0-0.rc0.20230501git58390c8ce1bd.10.eln126.x86_64.rpm
kernel-core-6.4.0-0.rc0.20230501git58390c8ce1bd.10.eln126.x86_64.rpm
kernel-modules-6.4.0-0.rc0.20230501git58390c8ce1bd.10.eln126.x86_64.rpm
kernel-modules-core-6.4.0-0.rc0.20230501git58390c8ce1bd.10.eln126.x86_64.rpm

2. Install them

Actual results:

Expected results: Installation completes

Additional info: The find_symvers_file function should be changed to

find_symvers_file() {
    local krel="$1"
    local print="$2"

    if find_kernel_file "$krel" symvers .gz > /dev/null; then
        find_kernel_file "$krel" symvers .gz "$print"
        return $?
    else
        find_kernel_file "$krel" symvers .xz "$print"
        return $?
    fi
}
