sci_stp_req...in_copy_data(9)

💅 sci_stp_req...in_copy_data(9) — the Kernel API Manual page, bestie edition 🎀

okay so before we even start: this is a page from the Kernel API Manual, and the star of the show is sci_stp_request_pio_data_in_copy_data. The real header up top literally truncates it to sci_stp_req...in_copy_data(9) because manpage headers have zero chill about column width. Anyway. Sit down, grab a snack, we're doing kernel internals 🍓

✨ NAME ✨

sci_stp_request_pio_data_in_copy_data —

(yes. that's it. that's the whole name section. no description. it's giving mysterious main character energy and honestly? respect 💅)

---

🌸 SYNOPSIS 🌸

enum sci_status sci_stp_request_pio_data_in_copy_data (struct isci_stp_request *stp_req , u8 *data_buffer );

so it returns an enum sci_status, takes two things, and lives its best life in the SCSI/ISCI corner of the kernel. no cap ✨

---

🦋 ARGUMENTS 🦋

• stp_req — the PIO DATA IN request that's about to receive the data. she's the recipient, the one getting the goods 🫶
• data_buffer — the buffer we're copying from. that's the source, the origin story, the "before" pic 📸

---

💖 DESCRIPTION 💖

okay so here's the whole vibe: this one copies the data buffer over to the io request data region. that's the entire job. like, she's not doing cardio, she's doing one thing and she's doing it 🎯

also, and I need you to know this because I refuse to edit the source material: the description in the original literally ends with the words enum sci_status just... chilling there. no context. no punctuation. it's giving typo that shipped. we keep it. we respect it. 🙈

lowkey no warnings, no bugs, no return-value drama on this page — it's a chill one. the only jump scare is that trailing enum sci_status. 💀

and that's the page!! this one ships out of ./drivers/scsi/isci and the date on the tin is October 2026, so mark your calendars bestie 🗓️✨ mwah, go copy some buffers responsibly 💜🧚‍♀️
