lpfc_sli_ringtx_get(9)

💖 lpfc_sli_ringtx_get(9) 💖

okay bestie, welcome to the Kernel API Manual page for lpfc_sli_ringtx_get(9) 🫶. This is the full group-chat explainer, and every arg, return detail, and SEE ALSO ref is staying exactly where it belongs — no cap 💅.

---

🌸 NAME 🌸

lpfc_sli_ringtx_get — Get first element of the txq ✨

---

🦋 SYNOPSIS 🦋

       struct lpfc_iocbq * lpfc_sli_ringtx_get (struct lpfc_hba *phba , struct
       lpfc_sli_ring *pring );

---

🎀 ARGUMENTS 🎀

• phba — Pointer to HBA context object. It's the HBA context object, periodt 💖.
• pring — Pointer to driver SLI ring object. That's the driver's SLI ring object right there 🌀.

---

💅 DESCRIPTION 💅

okay so real talk: this function is called with hbalock held, and its whole job is to get the next iocb in the txq of the given ring 👑.

If there is any iocb in the txq, the function returns the first iocb in the list after removing the iocb from the list. If there isn't one, it returns NULL — simple as that, bestie 😌.
