v9fs_alloc_rdir_buf(9)

💖 v9fs_alloc_rdir_buf — like, the whole manual tbh 🎀

okay so bestie, welcome to the v9fs_alloc_rdir_buf(9) page — yes that's the section 9 Kernel API Manual one, not one of your little section-1 girlies 💅. Sit down, hydrate, and let's get into it ✨

---

✨ NAME ✨

v9fs_alloc_rdir_buf — the lil function whose entire job is to allocate the buffer used for read and readdir. that's it. that's the whole vibe. it makes space so the reading can happen 🦋

---

🌸 SYNOPSIS 🌸

struct p9_rdir * v9fs_alloc_rdir_buf (struct file *filp , int buflen );

like, the way it returns a struct p9_rdir *… main character energy honestly 👑

---

🎀 ARGUMENTS 🎀

• filp — an opened file structure. you know, a struct file * — the file that's already been opened and is out here living its life 🫶
• buflen — the length in bytes of the buffer you want allocated. how much room are we giving it? that's buflen's whole moment, let her cook 🍓

bestie pls note: it just allocates. it does not fill the buffer, it does not read anything for you. set your expectations accordingly, no cap 🙈
