mas_store_gfp(9)

💖 mas_store_gfp(9) — like, the whole manual page, bestie 💖

okay so this is a page from the Kernel API Manual, and it's about mas_store_gfp(9) — yes the title is the same as the function name, iconic, we love a self-titled moment 👑

---

🌸 NAME 🌸

mas_store_gfp — Store a value into the tree.

that's it. that's the whole name section. short and slay ✨

---

🦋 SYNOPSIS 🦋

int mas_store_gfp (struct ma_state *mas , void *entry , gfp_t gfp );

so you call it, you give it three things, and it hands you back an int. that's the vibe check right there 🫶

---

🎀 ARGUMENTS 🎀

• mas — The maple state 💜 like, this is the state of your maple tree, your main character data structure, the thing you're operating on.
• entry — The entry to store 💅 this is the value actually going into the tree, bestie. the payload. the moment.
• gfp — The GFP_FLAGS to use for allocations if necessary 🔥 so if the store needs to allocate memory, these are the flags it gets to use. "if necessary" is doing a lot of work there, ngl.

---

⭐ RETURN ⭐

• 0 — on success 😌 slay, it worked
• -EINVAL — on invalid request 💀 the request was not it, invalid, rejected, denied
• -ENOMEM — if memory could not be allocated 😭 like the memory just wasn't there, no cap, it tried and it couldn't
