mtree_store_range(9)

🌸 mtree_store_range(9) — a lil' page from the Kernel API Manual 🎀

okay so bestie, this is mtree_store_range(9) and it lives in the Kernel API Manual, and honestly? it's giving "put a thing at a range of places in the maple tree" and it ate. let's get into it ✨

---

🦋 NAME 🦋

mtree_store_range — store an entry at a given range. that's it, that's the vibe. 💅

---

✨ SYNOPSIS ✨

int mtree_store_range (struct maple_tree *mt , unsigned long index ,
       unsigned long last , void *entry , gfp_t gfp );

look at her. five params, one int coming back, no notes. 👑

💖 ARGUMENTS 💖

• mt — the maple tree. your main character. the tree we're doing all this for 🌳
• index — the start of the range. where the whole thing begins, fr fr 📍
• last — the end of the range. the finish line, the closing bracket, the "and that's on periodt" 🎯
• entry — the entry to store. the actual thing you're yeeting in there 🫶
• gfp — the GFP_FLAGS to use for allocations. yes, the flags. the allocation vibes. that's the whole description and we respect it 🧚

---

🔥 RETURN 🔥

• 0 — success!! we love to see it 💖
• -EINVAL — invalid request. bestie that's not valid, we can't do that 🙈
• -ENOMEM — memory could not be allocated. literally the worst, no cap 😭

ngl bestie, that SEE ALSO list is long enough to need its own SEE ALSO. slay though, they're all iconic 👑

and that's the page!! sign-off time: this one came from the ./lib section, dated October 2026, and it's the mtree_store_range(9) manual page — go forth and store that range, you absolute icon 💜🦋⭐
