STRUCT DAMOS_ACCESS_PATTERN(9)

💖 NAME 💖

struct damos_access_pattern — the target access pattern of the given scheme, bestie. That's it, that's the vibe. ✨

Oh and hiii, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 🫶

---

✨ SYNOPSIS ✨

struct damos_access_pattern {
    unsigned long min_sz_region;
    unsigned long max_sz_region;
    unsigned int min_nr_accesses;
    unsigned int max_nr_accesses;
    unsigned int min_age_region;
    unsigned int max_age_region;
 };

okay so that's the whole shape of it, look at her 💅 six fields, all of them numbers, all of them doing the "what regions are we even talking about" job. Iconic.

🎀 Members 🎀

• min_sz_region — the minimum size of target regions. Like, if a region is smaller than this? Not invited to the party 🙈
• max_sz_region — the maximum size of target regions. And if it's bigger than this? Also not invited. Boundaries, bestie 💀
• min_nr_accesses — the minimum ->nr_accesses of target regions. Note the literal ->nr_accesses there, that's the field name, don't come for me 🌸
• max_nr_accesses — the maximum ->nr_accesses of target regions. Same field, other end of the range, no cap 🧢
• min_age_region — the minimum age of target regions. Youth check, lowkey 🦋
• max_age_region — the maximum age of target regions. Ok grandma let's get you to bed 👑

fr fr the whole point of this struct is: it's the target access pattern of the given scheme. It holds the range limits so the scheme knows which regions it's actually aiming at. That's the described purpose, nothing more, don't make me invent lore 😭

okay that's the whole page, go read the other 25, I believe in you 💜

and yeah — this one's sourced from ./include/linux, dated October 2026, and it's the struct damos_access_pattern(9) page, so you know exactly where you are 🎀 byeee bestie, mwah 💅✨
