memalloc_noreclaim_restore(9)

💅 memalloc_noreclaim_restore 💅

okay bestie, welcome to the Kernel API Manual corner where we handle the cleanup era of memory allocation flags. This one is short, iconic, and very much a “put it back the way you found it” situation. ✨

---

🎀 NAME 🎀

memalloc_noreclaim_restore — ends the implicit __GFP_MEMALLOC scope. periodt. 💅

---

✨ SYNOPSIS ✨

void memalloc_noreclaim_restore (unsigned int flags );

---

🌸 ARGUMENTS 🌸

• flags — the flags you’re restoring, bestie. That’s the whole assignment. 🫶

---

🦋 DESCRIPTION 🦋

okay so this function ends the implicit __GFP_MEMALLOC scope that was started by the memalloc_noreclaim_save function. It’s literally the “we’re done here, close the tab” of that pairing. 😌

⚠️ always — and I mean always — make sure the flags you pass in is the return value from the pairing memalloc_noreclaim_save call. no cap. that’s the whole vibe check. 💀
