🌸 release_recovery_journal_lock(9) — the Kernel API Manual glow-up 🎀

okay so bestie, this is the release_recovery_journal_lock page from the Kernel API Manual, and it's genuinely so much simpler than the giant SEE ALSO list makes it look. we're in ./drivers/md/dm-vdo territory, the slab journal is being a little diva, and our job here is one tiny thing: tell it to let go. 💅

✨ NAME ✨

release_recovery_journal_lock — ask the slab journal to release the recovery journal lock it might be holding on a specified recovery journal block. that's it. that's the whole vibe. 🫶

💖 SYNOPSIS 💖

bool release_recovery_journal_lock (struct slab_journal *journal ,
sequence_number_t recovery_lock );

yes the spacing is weird, no we're not fixing it, it's canon. 🙈

🦋 ARGUMENTS 🦋

  • journal — the slab journal. the main character of this whole function, lowkey. 👑
  • recovery_lock — the sequence number of the recovery journal block whose locks should be released. like, specifically that block's locks. not a different one. precision, bestie. ⭐

🌈 RETURN 🌈

returns True if the journal actually released a lock on the specified block. so a False here isn't a crime, it just means nothing got released — no cap. 💜

🔥 SEE ALSO 🔥

and now the part where the manpage shows off. i'm not skipping a single one of these, because the slab depot file is huge and every function in it deserves its moment. it's giving "tag yourself in the group chat" energy — Kernel file ./drivers/md/dm-vdo/slab-depot.c:

like. 130ish functions. the slab depot ate and left no crumbs. 💀✨

ngl bestie, this page is tiny — one function, one bool, one vibe check. so if you got here looking for the drama, the drama is all in SEE ALSO. go read release_journal_locks(9) if you want the group version of this. 🧚

and that's the whole page!! 💖 this little icon was brought to you by the fine folks at ./drivers/md/dm-vdo, dated October 2026 — go drink some water and close some file descriptors, mwah 🎀🦋🌸
