vdo_acquire_...ck_reference(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

ok so welcome to vdo_acquire_recovery_journal_block_reference(9) bestie!! this is a page from the Kernel API Manual, section (9) — yes, the function-name-up-top got chopped to vdo_acquire_...ck_reference(9) when they printed it, but that's just the header being dramatic, the real name is the whole long thing 💅

vdo_acquire_recovery_journal_block_reference — grab yourself a reference to a recovery journal block when you're coming from somewhere other than the journal itself. like, not the journal's own house, some other address, and you still need to hold a reference. iconic behaviour, no cap 🫶

✨ SYNOPSIS ✨

void vdo_acquire_recovery_journal_block_reference (struct
recovery_journal *journal , sequence_number_t sequence_number , enum
vdo_zone_type zone_type , zone_count_t zone_id );

that's it. that's the whole vibe. void, so it doesn't hand you anything back — it just does the thing 😌

🎀 ARGUMENTS 🎀

  • journal — the recovery journal. like, the actual journal we're referencing a block of. your main character 🫶
  • sequence_number — the journal sequence number of the referenced block. which block are we hyping up? this number says it. sequence_number_t fr fr.
  • zone_type — the type of the zone making the adjustment. enum vdo_zone_type, very official of it ✨
  • zone_id — the ID of the zone making the adjustment. zone_count_t, because zones are counted, periodt 💅

so just to be clear: it's journal, sequence number, zone type, zone id. four things. you're giving it four things. and it gives you back void. balanced, as all things should be 🌸

🦋 SEE ALSO 🦋

okay this list is long and honestly it ate, so buckle up bestie — every single one of these is a real reference, i'm not skipping a single one, that would be so not slay of me:

sixty-three entries and every one of them still got an invite to the group chat 🎉slay🎉

also there's a suspend_lock_counter(9) and a resume_lock_counter(9) in there, bestie. they're a matched set. i don't make the rules, the kernel does 💜

okay that's the whole page!! short and sweet and full of references, as a treat 🍓

signed off with love from the source dir ./drivers/md/dm-vdo, from the Kernel API Manual (vdo_acquire_...ck_reference(9)), dated October 2026 — i was literally born yesterday and i'm already documented, and that's on periodt ✨🎀💖
