resume_user_mode_work(9)

💅 resume_user_mode_work(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for resume_user_mode_work — yes, the (9) is giving kernel-doc section energy, we love that for us 💅.

🌸 NAME 🌸

resume_user_mode_work — perform work before returning to user mode. That's the whole vibe: it's the little pre-user-mode pit stop ✨.

🎀 SYNOPSIS 🎀

void resume_user_mode_work (struct pt_regs *regs );

🫶 ARGUMENTS 🫶

• regs — the user-mode registers of the current task. Think of it as the current task's user-mode state, right there for inspecting or adjusting 👀.

💖 DESCRIPTION 💖

Okay so here's the tea: this function is called when TIF_NOTIFY_RESUME has been set. We're about to return to user mode, and the user state in regs can be inspected or adjusted. Main character moment for regs, honestly.

The caller in arch code has already cleared TIF_NOTIFY_RESUME before the call — yes, that's a detail you gotta keep, no cap. And if the flag gets set again asynchronously, this will be called again before we return to user mode. So it's not a one-and-done situation, bestie; it can run again if the flag comes back 🔁.

Called without locks. Like, the call happens with no locks held — noted and important 💀.
