💖 struct perf_addr_filter(9) — address range filter definition 💖

okay so bestie, this is the Kernel API Manual, section 9, and we're talking about the absolute icon that is struct perf_addr_filter. It's giving "address range filter definition" and honestly? Obsessed. 🎀

🌸 NAME 🌸

✨ SYNOPSIS ✨

       struct perf_addr_filter {
           struct list_head                entry;
           struct path                     path;

• entry — event's filter list linkage; it's how this little guy is linked into the filter list, iykyk 🔗
• path — object file's path for file-based filters; yes, the actual path energy 🛤️
• offset — filter range offset, literally where the range starts ✨
• size — filter range size; and bestie, size==0 means single address trigger 🎯
• action — filter/start/stop; iconic trio, no notes 💅

🦋 Description 🦋

This is literally a hardware-agnostic filter configuration as specified by the user. Periodt. It's giving "the user said what they said" and the hardware just has to deal. 💖
