lpfc_release_nvme_buf(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to lpfc_release_nvme_buf(9) from the Kernel API Manual ✨ this is the page where a nvme buffer gets sent back home to the hba nvme buf list, and we're gonna understand it together. 💅

🎀 NAME 🎀

lpfc_release_nvme_buf — return a nvme buffer back to hba nvme buf list. That's the whole assignment, no cap. 🫶

✨ SYNOPSIS ✨

void lpfc_release_nvme_buf (struct lpfc_hba *phba , struct lpfc_io_buf
       *lpfc_ncmd );

💖 ARGUMENTS 💖

  • phba — the Hba for which this call is being executed. 👑
  • lpfc_ncmd — the nvme buffer which is being released. 🦋

🦋 DESCRIPTION 🦋

This routine releases the lpfc_ncmd nvme buffer by adding it to the tail of the phba lpfc_io_buf_list list. Literally just tucks it back onto the end of the list, bestie. 🎀

Heads up though: for SLI4, XRI's are tied to the nvme buffer, and they cannot be reused for at least RA_TOV amount of time if it was aborted. That's the caveat, okay? Don't forget it. 😭
