generic_pipe_buf_try_steal(9)

💅 generic_pipe_buf_try_steal — like, the kernel-API-manual-page-9 edition 🎀

okay so bestie, welcome to generic_pipe_buf_try_steal(9), from the Kernel API Manual (section 9, obviously, iykyk). this one is a little function with main character energy: it just wants to take a page and make it hers. let's get into it ✨

---

✨ NAME ✨

generic_pipe_buf_try_steal — attempt to take ownership of a &pipe_buffer 🫶

---

🌸 SYNOPSIS 🌸

bool generic_pipe_buf_try_steal (struct pipe_inode_info *pipe , struct
       pipe_buffer *buf );

literally that's it, two pointers and a bool. she's lowkey minimalist 💅

---

🦋 ARGUMENTS 🦋

• pipe — the pipe that the buffer belongs to. like, the whole situation this buffer is living in 🚰
• buf — the buffer to attempt to steal. yes. we're stealing it. not in a mean way. in a reuse way 🥰

---

💖 DESCRIPTION 💖

so this function attempts to steal the struct page attached to buf. iconique behavior, honestly.

if it's successful, this function returns 0 and returns with the page locked. and the caller may then reuse the page for whatever he wishes — the typical use is insertion into a different file page cache. no cap, that's the whole vibe: snatch the page, lock it, hand it off, go put it somewhere else 🌈

ngl, returning 0 from a bool on success is giving "we don't follow the rules, we are the rules". just letting you know what the page says, bestie, don't come for me 💀
