generic_pipe_buf_get(9)

💖 generic_pipe_buf_get(9) 💖

okay bestie, welcome to the generic_pipe_buf_get page — it's a Kernel API Manual moment and honestly it's giving "small function, big responsibility" 💅

---

✨ NAME ✨

generic_pipe_buf_get — grab a reference to a &struct pipe_buffer

like, an extra reference. we're adding to the count, not replacing anything 🫶

---

🌸 SYNOPSIS 🌸

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

yes that's the whole signature, wrapped exactly like the original, no cap ✨

---

🎀 ARGUMENTS 🎀

• pipe — the pipe that the buffer belongs to. it's the home base, the main character pipe in question 🧚
• buf — the buffer you're getting a reference to. this is the one we're hyping up 💜

---

🦋 DESCRIPTION 🦋

so what does it actually do? it grabs an extra reference to buf. literally that's the whole vibe 🔥

where you'll see it: in the tee system call, when we duplicate the buffers in one pipe into another. that's the moment — the crossover episode 👑

---

🌈 SEE ALSO 🌈

• Kernel file ./fs/pipe.c
• generic_pipe_buf_try_steal(9)
• generic_pipe_buf_release(9)

go read those next, iykyk 📚

ngl this page is short but it ate. extra refs are serious business — don't lose track of them or the vibe check fails 😭

---

mwah 💋 that's a wrap! this one lives in ./fs, and the manual's dated October 2026 — so yes, the docs are booked and busy, see you in the future bestie ⭐🎀
