jbd2_journal_load(9)

✨ NAME ✨

okay so bestie, welcome to jbd2_journal_load(9) from the Kernel API Manual 💖 — this page is literally about reading the journal from disk.

🌸 SYNOPSIS 🌸

int jbd2_journal_load (journal_t *journal );

🎀 ARGUMENTS 🎀

• journal — the journal to act on, like, the journal_t you’re handing over to do its thing.

🦋 DESCRIPTION 🦋

Picture this: you’ve got a journal_t structure that tells us which disk blocks contain a journal. jbd2_journal_load reads that journal from disk to initialise the in-memory structures. That’s the whole vibe check: disk journal comes in, in-memory structures get set up. No cap. 💅
