rvt_update_mmap_info(9)

🌸 NAME 🌸

okay so bestie, this is the rvt_update_mmap_info(9) page from the Kernel API Manual. The NAME line keeps it simple: rvt_update_mmap_info - update a mem map. 💅 Small name, clear job, iconic behavior.

✨ SYNOPSIS ✨

Here's the signature, copy-paste exact, don't let autocorrect touch it:

void rvt_update_mmap_info (struct rvt_dev_info *rdi , struct
       rvt_mmap_info *ip , u32 size , void *obj );

It returns void, so no return value era — we move. 🫶

💖 ARGUMENTS 💖

Four things walk into the function, and here's the whole guest list:

• rdi — the rvt dev struct. That's it, that's the vibe.
• ip — the mmap info pointer. The pointer itself, front and center.
• size — the size to grow by. Number go up by this much, periodt.
• obj — an opaque pointer to a cq, wq, etc. Opaque pointer, cq, wq, etc. — all the exact deets are right there, iykyk. 💀
