diag_cmd_data_free(9)

💖 diag_cmd_data_free(9) — from the Kernel API Manual, bestie 💖

okay so picture this: you're deep in lpfc land, and something's gotta get cleaned up. That's the whole vibe of this page. Welcome to the Kernel API Manual, function number 9 in the section, and honestly? She's a little legend. 🫶

✨ NAME ✨

diag_cmd_data_free — literally just frees an lpfc dma buffer extension. That's it. That's the whole job. No cap. 💅

---

🌸 SYNOPSIS 🌸

int diag_cmd_data_free (struct lpfc_hba *phba , struct lpfc_dmabufext
*mlist );

ok so real talk, the signature got line-wrapped in the original and we're keeping it exactly as-is because ✨ fidelity ✨. It returns an int, it takes two pointers, and yes, one of them is named mlist and the other is named phba. Iconic naming choices honestly. 🎀

---

🦋 ARGUMENTS 🦋

• phba — pointer to the HBA context object. Like, the whole adapter's context. She's the main character here, everything comes back to her. 👑
• mlist — pointer to an lpfc dma buffer extension. The thing that's about to get freed. Say your goodbyes bestie. 😭

ngl both of these are just pointers, but they're important pointers. Don't be out here passing random garbage, fr fr. 🙈

🌈 SEE ALSO 🌈

ok this list is LONG and I respect it deeply. Every single one of these, present and accounted for, no skipping, no summarizing, we don't do that here. 💜
