qla29xx_copy_dif_iocb_data(9)

🦋 qla29xx_copy_dif_iocb_data(9) — the Kernel API Manual glow-up 🦋

okay bestie, so this one is a Kernel API Manual page, section 9, and it's literally about one little helper that fills in the DIF-flavored bits of an extended CRC_2 command IOCB using a crc_context you just populated. it's giving "glorified copy-paste but make it SCSI" 💅

---

✨ NAME ✨

qla29xx_copy_dif_iocb_data — bestie's job is to populate the DIF-related fields of an extended CRC_2 command IOCB, pulling from a freshly populated crc_context. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void qla29xx_copy_dif_iocb_data (struct cmd_type_crc_2_ext *cmd_pkt ,
struct crc_context *crc_ctx_pkt , uint8_t dif_bundling );

no return value, queen — it's void, it just does the thing and leaves. main character energy fr fr ✨

---

💖 ARGUMENTS 💖

• cmd_pkt — the extended CRC_2 command IOCB 💫 this is the destination, the one getting its DIF-related fields filled in.
• crc_ctx_pkt — the source CRC context 🌈 this is where the data comes from, and it's gotta be freshly populated before you call this.
• dif_bundling — the DIF bundling flag (uint8_t) 🎀 yes it's literally just the flag, and yes it matters, iykyk.

ngl there's no exit status, no signals, no environment variables and no error list on this page — it's a void function and it simply vibes. don't go inventing drama that isn't in the docs, bestie 🙈
