💖 lpfc_nvmet_buf_alloc(9) — Kernel API Manual 💖

okay so bestie, welcome to the lpfc_nvmet_buf_alloc(9) page from the Kernel API Manual — it's giving “grab me an nvmet_buf from the lpfc_sg_dma_buf_pool PCI pool” energy, and honestly? iconic. 💅✨

✨ NAME ✨

lpfc_nvmet_buf_alloc — Allocate an nvmet_buf from the lpfc_sg_dma_buf_pool PCI pool 🎀

🌸 SYNOPSIS 🌸

void * lpfc_nvmet_buf_alloc (struct lpfc_hba *phba , int mem_flags ,
       dma_addr_t *handle );

🦋 ARGUMENTS 🦋

• phba — the HBA that owns the pool we're allocating from. like, the main character holding the stash 🫶
• mem_flags — tells you if this is a priority allocation (MEM_PRI). priority means priority, bestie 💅
• handle — used to return the DMA-mapped address of the nvmet_buf 📬

🔥 DESCRIPTION 🔥

Allocates a DMA-mapped buffer from the lpfc_sg_dma_buf_pool PCI pool. It allocates from the generic dma_pool_alloc function. no cap, that's the whole move ✨

🌈 RETURN 🌈

On success, you get a pointer to the allocated nvmet_buf; on failure, NULL. that's it — success pointer, failure NULL, periodt 💀
