syscall_exit_work(9)

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

okay so picture this: you're a syscall, you've done your little tasks, and now you're this close to sliding back into user mode. but before you go — there's a tiny bit of cleanup. that's this function. she's the last vibe check before you leave the building. ✨

✨ NAME ✨

syscall_exit_work — handle work before returning to user mode 🫶

---

🌸 SYNOPSIS 🌸

void syscall_exit_work (struct pt_regs *regs , unsigned long work );

---

🦋 ARGUMENTS 🦋

• regs — pointer to the current pt_regs. literally the receipts of where your registers are at rn. 💅
• work — the current thread syscall work. this is the to-do list she's carrying out the door. 📋

---

💖 DESCRIPTION 💖

do one-time syscall specific work.

that's it. that's the whole description. she's lowkey iconic for being this short about it. one-time, syscall-specific, and then you're free. no cap. 🧚

reminder bestie: this page is short on purpose. don't go inventing behaviour that isn't written here — if it's not in the description, it's not canon. 🙈

⭐ and that's the page! brought to you from ./include/linux, dated October 2026, and yes the footer still says syscall_exit_work(9) because we never forget where we came from. mwah 💋👑🌈
