xe_mem_pool_alloc_node(9)

✨ xe_mem_pool_alloc_node ✨

okay bestie, welcome to xe_mem_pool_alloc_node(9) — yes the (9) means kernel API manual, we're in the big pages now 💅 this one lives in the Linux kernel API manual, and honestly it's a little cutie: it does exactly one thing and it does it slayfully.

---

🌸 NAME 🌸

xe_mem_pool_alloc_node — allocate a new node for use with xe_mem_pool.

like, that's it. that's the whole vibe. one node, freshly allocated, ready to be part of the pool 🫶

---

🎀 SYNOPSIS 🎀

struct xe_mem_pool_node * xe_mem_pool_alloc_node (void );

no cap, look at that signature. returns a pointer to a struct xe_mem_pool_node, takes literally nothing. icon behavior ✨

---

🦋 ARGUMENTS 🦋

• void — no arguments. not one. zero. the void is voiding 🙈 nothing to pass in, nothing to worry about, just call it and go.

---

💖 RETURN 💖

on success you get a node structure back 🎉 and if things go sideways? you get an ERR_PTR(-ENOMEM). that means the allocation failed because memory said "not today" 😭 so like, always check it with IS_ERR() before you go dereferencing, bestie, that's not a drill.

memory allocation can fail — treat ERR_PTR(-ENOMEM) as a real possibility, not a decorative footnote 🔥
