From: Quentin Monnet <quentin@xxxxxxxxxxxxx> [ Upstream commit 4eeebce6ac4ad80ee8243bb847c98e0e55848d47 ] The script for checking that various lists of types in bpftool remain in sync with the UAPI BPF header uses a regex to parse enum bpf_prog_type. If this enum contains a set of values different from the list of program types in bpftool, it complains. This script should have reported the addition, some time ago, of the new BPF_PROG_TYPE_SYSCALL, which was not reported to bpftool's program types list. It failed to do so, because it failed to parse that new type from the enum. This is because the new value, in the BPF header, has an explicative comment on the same line, and the regex does not support that. Let's update the script to support parsing enum values when they have comments on the same line.
