watch_sizeof(9)

💅 watch_sizeof(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're in the kernel source, you've got a watch record, and you need to know how big the information part of it is when you already know the size of the struct. that's literally the whole gig of watch_sizeof. it's a size calculator for watch records and it is doing exactly one (1) thing. iconic behaviour honestly.

✨ NAME ✨

watch_sizeof — calculate the information part of the size of a watch record, given the structure size. that's it, that's the function, no cap 🫶

---

🌸 SYNOPSIS 🌸

watch_sizeof (STRUCT );

copy it exactly like that, yes including the spacing, do not come for me, I don't write the headers I just report them 💀

---

🦋 ARGUMENTS 🦋

• STRUCT — so… the manpage literally says -- undescribed --. that's not me being lazy bestie, that is the actual state of the documentation 😭 the parameter exists, it's called STRUCT, and nobody wrote down what it is. we simply do not know. mystery main character energy.

real talk: if you need to actually know what STRUCT wants from you, the manpage is not gonna help and neither am I — that's a "go read the header" situation, bestie. go read the header 🧚

⭐ SEE ALSO ⭐

• Kernel file ./include/linux/watch_queue.h — go look at the source, it's right there, it's giving "the answer key is in the back of the book" 💖

this lil page lives in ./include/linux, and it is dated October 2026 — so yeah, it's a lil time traveller, we love that for it 🌈 hope you found what you needed, mwah, go read watch_queue.h 💜💅
