💅 folio_try_get(9) — Kernel API Manual ✨

okay so bestie, welcome to the manual page for folio_try_get(9) from the Kernel API Manual — yes, the manual name is right here near the top like a lil name tag, because we're not doing the boring copied header line. 💖

📛 NAME 📛

folio_try_get — attempt to increase the refcount on a folio. That's the whole assignment, no cap. 🫶

🛠️ SYNOPSIS 🛠️

bool folio_try_get (struct folio *folio );

🎀 ARGUMENTS 🎀

• folio — the folio. like, the actual folio. periodt. 💅

💫 DESCRIPTION 💫

So here's the tea: if you do not already have a reference to a folio, you can attempt to get one using this function. It may fail if, for example, the folio has been freed since you found a pointer to it, or it is frozen for the purposes of splitting or migration. No cap, those are real failure vibes. 😭

✅ RETURN ✅

True if the reference count was successfully incremented. That's the slay condition — refcount bumped, you get the true-yes. ✨
