mega_allocate_scb(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mega_allocate_scb(9) — the Kernel API Manual tea ☕✨

okay so before we even start: yes, this is that mega_allocate_scb(9) page from the Kernel API Manual. buckle up bestie, it's a short one but it's lowkey important 🫶

🌸 NAME 🌸

mega_allocate_scb — and that's it. that's the whole name section. the original literally gives us nothing after the dash 😭 no description, no tagline, nada. iconic honestly, she said "read the next section diva" 💀

✨ SYNOPSIS ✨

scb_t * mega_allocate_scb (adapter_t *adapter , struct scsi_cmnd *cmd );

so it hands you back a scb_t * — a pointer to an SCB structure — and it takes exactly two things. no cap, that's the whole signature 🔥

🎀 ARGUMENTS 🎀

  • adapter — pointer to our soft state, i.e. this is your adapter's own little stash of state. you're passing it in, it's your responsibility, ngl 💅
  • cmd — the scsi command coming down from the mid-layer. it's giving "the actual work order arriving from above" ✨

🦋 DESCRIPTION 🦋

so what does she do? she allocates an SCB structure. that's the vibe check 🌈

and not just any structure — this one is the central structure for controller commands. like, main character energy of the whole command path. everything funnels through this bad boy 👑

fr fr, if you're in megaraid land, the SCB is the thing. build it right or everything downstream is a mess 💀

👑 SEE ALSO 👑

buckle up, this list is long — honestly she ate with the cross-references 🍓 also note the kernel file lives at ./drivers/scsi/megaraid.c, so that's your address for all of these besties:

and that's the whole page, bestie!! 💜 tiny page, huge responsibility. go read mega_init_scb(9) next if you wanna be thorough, mwah 💋

signing off from ./drivers/scsi — dated October 2026 — still serving mega_allocate_scb(9) realness 🎀✨ see u in the kernel sources 🫶
