wb_dying(9)

💅 NAME 💅

okay so this is wb_dying(9), straight from the Kernel API Manual, and it's literally just asking: is this wb dying? bestie, that's the whole assignment. 💖

✨ SYNOPSIS ✨

bool wb_dying (struct bdi_writeback *wb );

🎀 ARGUMENTS 🎀

• wb — the bdi_writeback of interest, aka the one we're giving a vibe check. 🫶

🦋 DESCRIPTION 🦋

It tells you whether wb is unlinked and being drained. That's it. That's the whole vibe check. No cap, no extra lore. ✨

bestie please note: the answer is a bool, so it's giving yes/no energy, not a whole essay. 💅
