locks_end_grace(9)

💅 locks_end_grace — the "we're so back" button for grace periods

okay so this is a page from the Kernel API Manual (yes, locks_end_grace(9), that one) and bestie, it's a short one but it matters. Let's get into it ✨

---

🌸 NAME

locks_end_grace — and that's it. That's the whole description. The original page literally leaves it blank, and honestly? Iconic minimalism. Main character energy: shows up, says nothing, leaves 💅

---

✨ SYNOPSIS

void locks_end_grace (struct lock_manager *lm );

That's the whole vibe. One function, one argument, no return value, no drama 🎀

---

🫶 ARGUMENTS

• lm — who this grace period is for. Like, which lock manager are we closing out the grace period for? That's lm. That's it. That's the whole argument 🦋

---

💖 DESCRIPTION

Okay so here's the tea ☕ — you call this function to state that the given lock manager is ready to resume regular locking. Think of it as texting "omw home" — you're signalling you're done with the grace period era and ready to go back to normal.

But here's the part you cannot skip: the grace period will not end until all lock managers that called locks_start_grace also call locks_end_grace. It's giving group project. Everyone has to turn in their part or nobody gets to move on 😭 No cap, it waits for all of them.

And lowkey the important bit: callers count on it being safe to call this more than once, and the second call should be a no-op. So like, don't panic if it gets called twice — it's built different, it handles it. Second time around it just vibes and does nothing 🌈

• locks_in_grace(9) — the one that checks if we're still in it ⭐

fr fr that's the whole page — short, sweet, and absolutely essential to the kernel's locking situation 💜

mwah, this page came from ./fs/nfs_common, dated October 2026, and it will forever be known as locks_end_grace(9) 🎀✨💅
