dc_check_add..._only_update(9)

🫶 dc_check_address_only_update(9) — straight from the Kernel API Manual 💅

okay so bestie, this is the Kernel API Manual page for a tiny little kernel check, and it is literally one job. No cap. Let's do the vibe check ✨

🌸 NAME 🌸

dc_check_address_only_update — check if addr_update is the sole flag set 💖

✨ SYNOPSIS ✨

bool dc_check_address_only_update (struct pipe_update_bits update_bits
);

🎀 ARGUMENTS 🎀

• update_bits — the pipe update bits to check, bestie. That's the thing getting inspected. 🫶

💖 DESCRIPTION 💖

Okay so listen: this function determines whether an update contains only an address change with no other pending updates. That's the whole assignment. It's giving “just an address change, nothing else pending” energy, and honestly? Obsessed. 👑

No side quests, no extra pending updates — just the address-change situation. ✨

🔥 RETURN 🔥

• true — if addr_update is the sole bit set. Slay. 💅
• false — otherwise, bestie. 💀
