💖 NAME 💖

rvt_check_refs — check references 🔍

---

🎀 SYNOPSIS 🎀

int rvt_check_refs (struct rvt_mregion *mr , const char *t );

---

🌸 ARGUMENTS 🌸

• mr — the megion 👑 (yes, that's exactly what the page says, and we're respecting it fr fr)
• t — the caller identification 🪪 like, who even are you, bestie?

---

🦋 DESCRIPTION 🦋

so this routine checks MRs holding a reference during when being de-registered. highkey a whole vibe check for references mid-deregistration ✨

if the count is non-zero, the code calls a clean routine then waits for the timeout for the count to zero. it's giving "hold on, we're not done yet" energy 😭⏳
