💖 __orc_alloc_scb(9) — Kernel API Manual, bestie edition 🌸

okay so real talk, this whole page lives in the Kernel API Manual and honestly? it's a short one. but short ≠ skip-able, so grab your iced coffee and let's go ✨

✨ NAME ✨

__orc_alloc_scb — allocate an SCB 🎀

like, that's it. that's the whole job. it allocates an SCB. no cap.

🦋 SYNOPSIS 🦋

struct orc_scb * __orc_alloc_scb (struct orc_host * host );

🌸 ARGUMENTS 🌸

  • host — the host you're allocating from, i.e. the whole vibe source for this SCB 🫶

💜 DESCRIPTION 💜

So what this does is: it allocates an SCB and hands you back a pointer to that SCB object. iconic behavior tbh 👑

But heads up — if there is no SCB free, you get NULL back. not an error, not a warning, just NULL. so check it, bestie 😭

⚠️ huge one: the caller must already hold the allocator lock at this point. like, not "should", not "probably" — must. this function is not out here doing its own locking, iykyk. come correct or don't come at all 💅

that's the page!! source/location is ./drivers/scsi and the date on this beauty is October 2026 — go forth, hold that allocator lock, and slay 💅💖⭐
