syscall_exi...mode_prepare(9)

🌸 NAME 🌸

syscall_exit_to_user_mode_prepare — the girlie that calls exit_to_user_mode_loop() if it's, like, actually required 💅

---

✨ SYNOPSIS ✨

void syscall_exit_to_user_mode_prepare (struct pt_regs *regs );

---

🎀 ARGUMENTS 🎀

• regs — pointer to pt_regs on the entry stack, bestie. That's the whole vibe. 🫶

---

💖 DESCRIPTION 💖

Okay so real talk: this function is a wrapper around __exit_to_user_mode_prepare, and its whole job — its entire main character energy — is to separate the exit work for syscalls and interrupts. That's it. That's the lore. 🔥

Like, syscalls and interrupts both gotta exit to user mode eventually, but they do NOT share the same exit-work pipeline, and this lil function is the one keeping those two worlds apart so nothing gets messy. No cap. ✨
