vdo_uses_bio_ack_queue(9)

okay bestie, welcome to the Kernel API Manual corner of the group chat — this one is vdo_uses_bio_ack_queue(9), and it’s giving tiny-but-mighty helper energy ✨

🎀 NAME 🎀

vdo_uses_bio_ack_queue — tells you whether the vdo is configured to use a separate work queue for acknowledging received and processed bios. no cap 💅

---

🌸 SYNOPSIS 🌸

bool vdo_uses_bio_ack_queue (struct vdo *vdo );

---

🦋 ARGUMENTS 🦋

• vdo — the vdo. that’s literally the whole argument, bestie 🫶

---

💖 DESCRIPTION 💖

real talk: this directly controls the handling of write operations. but there’s a plot twist for reads — the compile-time flag VDO_USE_BIO_ACK_QUEUE_FOR_READ is also checked for read operations. so writes are handled by this, and reads also get that flag in the mix 👑

---

⭐ RETURN ⭐

returns whether a bio-acknowledgement work queue is in use. yes/no bool energy, iconic 🎀

that’s the whole page, bestie 💜 — source/version: ./drivers/md/dm-vdo, dated October 2026. go off and check your queues responsibly ✨💅
