💅 get_reference_counters_for_block

Okay so this one's from the Kernel API Manual (yes, the Kernel API Manual — we're in the big leagues now, bestie 🫶), and it's genuinely one of the shorter ones, which honestly? We love a low-effort slay. Grab a strawberry 🍓 and let's get into it.

✨ NAME ✨

get_reference_counters_for_block — find the reference counters for a given block. That's it, that's the whole gig. Short, sweet, iconic. 👑

🌸 SYNOPSIS 🌸

vdo_refcount_t * get_reference_counters_for_block (struct
       reference_block *block );

Not me writing a function signature that just… is that. No tricks, no secret extra args, no little surprises hiding in there. She said what she said. 💅

🦋 ARGUMENTS 🦋

  • block — the reference_block in question. Like, the actual block you're asking about, bestie. The one in question!! 🎀

⭐ RETURN ⭐

A pointer to the reference counters for this block. vdo_refcount_t *, to be specific. So you get a pointer back — not the counters themselves, the pointer — and honestly that's the whole vibe: it's giving "here's the address, go off." ✨

Ngl, that's the entire documented return. No error case written down here, so I'm not gonna invent one for clout. 🫶

💜 SEE ALSO 💜

Okay so this page is lowkey a gateway — the real content lives in the kernel file ./drivers/md/dm-vdo/slab-depot.c, and the see-also list is genuinely a whole group chat. Buckle up, because I'm listing every single one, fr fr. 😭

Like I said — whole group chat. Every single one of them is in ./drivers/md/dm-vdo/slab-depot.c, iykyk. 🔥

That's the page, bestie! Shoutout to the source tree ./drivers/md/dm-vdo and the date stamp October 2026 — that's the version-and-date energy right there. Go read the actual source, it ate. 💅✨🎀
