Feature description

Events that include files information in their arguments tend to have many arguments (sched_process_exec is the extreme example for it). To reduce the amount of arguments and make it more user friendly, I propose to create a FileInfo struct to contain the data that is always passed by events on files - path, device, inode and ctime. This change will probably break many rules for our users, but will improve the accessibility for new users. WDYT?

In terms of style, I personally like this better.

Regarding the backwards compatibility issue, maybe for now we can only add the new arg and then deprecate the old args in a later version? We're not v1 yet so we can allow breaking changes, as we've done before, but this is a commonly used event in signatures as you noted. Either way, this does raise again the need to implement a versioning strategy for our types.
