💖 jbd2_journal_clear_err(9) — the kernel API manual page, bestie edition 💖

okay so this is the page for jbd2_journal_clear_err from the Kernel API Manual, and honestly? it's a short one but it's iconic. it's giving "one job, does it perfectly" energy. let's get into it ✨

🌸 NAME 🌸

jbd2_journal_clear_err — clears the journal's error state 🧹💅

like yes, that's it, that's the whole assignment, and she ate.

🦋 SYNOPSIS 🦋

int jbd2_journal_clear_err (journal_t *journal );

look at her. one function, one pointer, one int return. clean lines, no notes, main character energy fr fr 👑

🎀 ARGUMENTS 🎀

  • journal — journal to act on. 🫶 that's the journal_t * bestie, the thing you're clearing the error state on. that's her. that's the target.

⭐ DESCRIPTION ⭐

okay so here's the actual tea ☕: an error must be cleared or acked to take a FS out of readonly mode.

read that again. no cap. if your filesystem is sitting there in readonly mode being all dramatic 💀, clearing the error (or acking it) is literally how you get it out. so jbd2_journal_clear_err is highkey doing emotional support AND structural support at the same time. we love a multitasker 🧚💜

no like literally, that's the whole description. it's short but it's LOAD-BEARING. don't skip it. 🙈

🌈 SEE ALSO 🌈
