💅 rdma_user_mmap_entry_get(9) 💅

okay so welcome to the Kernel API Manual page for rdma_user_mmap_entry_get(9) — bestie, we are getting an entry from the mmap_xa and it's giving kernel-core realness ✨

🌸 NAME 🌸

rdma_user_mmap_entry_get — get an entry from the mmap_xa, periodt 💖

✨ SYNOPSIS ✨

struct rdma_user_mmap_entry * rdma_user_mmap_entry_get (struct
ib_ucontext *ucontext , struct vm_area_struct *vma );

🎀 ARGUMENTS 🎀

• ucontext — the associated user context. yep, that user context 🫶
• vma — the vma being mmap'd into. the VMA in question, bestie 💅

🦋 DESCRIPTION 🦋

This function is like rdma_user_mmap_entry_get_pgoff, except that it also checks that the VMA is correct. so it's the same vibe plus a VMA check — iconic behavior, no cap 🔥

this one cares about the VMA being correct, so don't skip that part 😤
