Subject: selftests/bpf: Reject unsupported -k option in vmtest.sh
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6df582112aa9ac9d190169abdb0e42e496659ec9;p=thirdparty%2Fkernel%2Flinux.git

selftests/bpf: Reject unsupported -k option in vmtest.sh

vmtest.sh does not document a -k option and does not handle it in the
getopts case statement. However, the getopts optstring includes k, which
causes the script to accept -k silently instead of reporting it as an
invalid option.

Remove k from the optstring so unsupported options are rejected through
the existing invalid-option path.

Fixes: c9709f52386d ("bpf: Helper script for running BPF presubmit tests")
