💖 amdkfd_fence_check_mm — the kernel API manual, but make it group chat 💖

okay so bestie, welcome to the amdkfd_fence_check_mm(9) page ✨ this is a kernel API manual moment, and honestly? it's giving "small function, big responsibility" 🎀 we're checking whether we should prevent eviction of @f by @mm, and yes the @s are staying because they're iconic 💅

🦋 SYNOPSIS 🦋

bool amdkfd_fence_check_mm (struct dma_fence *f , struct mm_struct *mm
);

literally that's the whole signature, no cap 🔥 returns a bool, takes a struct dma_fence * and a struct mm_struct *, and that's it 🫶

🌸 ARGUMENTS 🌸

• f — [IN] the fence 🧚 this is the one we're checking against, main character energy fr
• mm — [IN] the mm that needs to be verified 💜 the one we're putting under the magnifying glass 🔍

👑 DESCRIPTION 👑

so here's the vibe check: check if mm is the same as that of the fence f 💫 if it's the same, return TRUE ⭐ if it's not, return FALSE 💀 that's the entire plot, and honestly it ate 🌈
