jbd2_journal_force_commit(9)

💅 jbd2_journal_force_commit(9) 💅

okay bestie, we're in the Kernel API Manual now — this is the page for jbd2_journal_force_commit, and it's lowkey about forcing commits. let's get into it 🫶

💖 NAME 💖

jbd2_journal_force_commit — force any uncommitted transactions. that's the whole name, and it ate ✨

✨ SYNOPSIS ✨

int jbd2_journal_force_commit (journal_t *journal );

it's giving int, and it takes a journal_t *journal. periodt.

🎀 ARGUMENTS 🎀

• journal — journal to force. yes, that's the journal you're forcing, bestie 🎀

🦋 DESCRIPTION 🦋

okay so the caller wants an unconditional commit — no cap, they want the commit to happen, no conditions attached.

but here's the real tea: we can only force the running transaction if we don't have an active handle.

⚠️ if there is an active handle, we will deadlock 😭💀 — not cute, not slay, just a whole hang. so this is very much a "know what you're doing" situation, fr fr.
