✨ NAME ✨

---

🌸 SYNOPSIS 🌸

void drm_pagemap_release_owner (struct drm_pagemap_peer *peer );

like, that's the whole signature. void return, so nothing comes back — it just does the thing and dips 💨

---

🎀 ARGUMENTS 🎀

• peer — a pointer to the struct drm_pagemap_peer that you used way back when you joined the group in the first place. yes, the same one. don't show up with a different one, that's not the vibe 🙈

---

🦋 DESCRIPTION 🦋

so basically: stop participating in an interconnect group. that's it, that's the whole gig ✨

this function is typically called when a pagemap is removed, and it's literally just you raising your hand and being like "hey so I don't need to be taken into account anymore, kthx" 💅 it's the graceful exit. the irish goodbye. the "not me being perceived" moment.
