Hi Fernando,

The syntax seems overly complicated to me, although I'm not really
familiar with OSF so may lack background knowledge. Any reason why you
didn't go with 'osf ttl skip name "Linux" version "4.20"' instead?

Also with regards to your patch to json_parser, I guess you should
introduce an enum for flag values, something like:

| enum osf_flags {
| 	OSF_FLAG_INVALID = 0x0,
| 	OSF_FLAG_VERSION = 0x1
| };
| 
| const char *osf_flag_names[] = {
| 	[OSF_VERSION] = "version"
| };

What do you think?

Cheers, Phil
