commit cdb50525345cf5a8359ee391032ef606a7826f08 upstream.
Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features.
Here are some helpers that will be used to mark subtests as skipped if a feature is not supported. Marking as a fix for the commit introducing this selftest to help with the backports.
While at it, also check if kallsyms feature is available as it will also be used in the following commits to check if MPTCP features are available before starting a test.
