do_commit(9)

💅 do_commit(9) 💅

okay so this page is from the Kernel API Manual, and it's giving "commit the journal" main character energy. bestie, let's get into it 🫶✨

---

🌸 NAME 🌸

do_commit — commit the journal. periodt 💖

---

✨ SYNOPSIS ✨

int do_commit (struct ubifs_info *c );

---

🎀 ARGUMENTS 🎀

• c — UBIFS file-system description object. that's the whole arg, no cap 🦋

---

🔥 DESCRIPTION 🔥

So this function implements UBIFS commit. literally its whole thing ✨

⚠️ heads up bestie: it has to be called with commit lock locked. not optional, not a vibe, it's required 💅

It returns zero in case of success and a negative error code in case of failure. so: 0 = slay, negative = something went off 😭
