💅 mpt3sas_ctl_done — the ctl module completion routine bestie ✨

okay so real quick, before we get into it: this one's a kernel API manual page, page name mpt3sas_ctl_done, and it lives in the kernel docs. it's short, it's sweet, and it's the little callback that could 🫶

✨ NAME ✨

mpt3sas_ctl_done — literally the ctl module completion routine. that's her job. that's what she does 💅

🦋 SYNOPSIS 🦋

u8 mpt3sas_ctl_done (struct MPT3SAS_ADAPTER *ioc , u16 smid , u8
msix_index , u32 reply );

yes she returns a u8, yes she takes four args, no we're not scared of her 💖

🎀 ARGUMENTS 🎀

  • ioc — the per adapter object. your whole adapter's whole personality lives here 🌸
  • smid — system request message index. it's the little name tag for the message, iykyk 🔖
  • msix_index — the MSIX table index supplied by the OS. the OS handed it over, we just hold it 🫶
  • reply — reply message frame (lower 32bit addr). lowercase bit, exact spelling, don't come for me 😭

💀 CONTEXT 💀

none. that's it. that's the whole section. no context, no vibes to check, nothing 🧚

🔥 DESCRIPTION 🔥

so the actual tea: this is the callback handler when using ioc->ctl_cb_idx. that's the entire description and honestly she ate 💅✨

👑 RETURN 👑

  • 1 — meaning the mf should be freed from _base_interrupt 💀
  • 0 — means the mf is freed from this function 🙈

no cap, those are the only two options, and yes the wording is exactly like that, I'm not editing it, it's iconic.
