rvt_alloc_rq(9)

💖 NAME 💖

okay so bestie, welcome to the rvt_alloc_rq(9) page from the Kernel API Manual ✨ this one is literally rvt_alloc_rq — allocate memory for user or kernel buffer 💅

✨ SYNOPSIS ✨

int rvt_alloc_rq (struct rvt_rq *rq , u32 size , int node , struct
       ib_udata *udata );

🎀 ARGUMENTS 🎀

• rq — receive queue data structure 💖
• size — number of request queue entries
• node — The NUMA node
• udata — True if user data is available or not false

(no cap, that's the exact udata wording — we're not fixing it, we're respecting the lore 🫶)

😭 RETURN 😭

If memory allocation failed, return -ENONEM (yes, that spelling — don't come for me, I'm just the messenger 💀). This function is used by both shared receive queues and non-shared receive queues to allocate memory. periodt.
