vdo_synchronous_flush(9)

💅 vdo_synchronous_flush — like, the Kernel API Manual page, bestie ✨

okay so picture this: it's giving kernel API manual energy, it's a <pink>(9)</> page, and the whole personality is "flush it and wait". Let's go 🫶

---

🌸 NAME 🌸

vdo_synchronous_flush — issue a flush request and wait for it to complete. yeah. that's the whole job. it flushes, it waits, it slays 💅✨

---

🎀 SYNOPSIS 🎀

int vdo_synchronous_flush (struct vdo *vdo );

literally just hand it a vdo and it gives you back an int. no cap.

---

🦋 ARGUMENTS 🦋

• vdo — the vdo. that's it. that's the argument. the vdo in question. iconic, honestly 👑

---

⭐ RETURN ⭐

VDO_SUCCESS or an error. so like... it either ate or it didn't, and you'll know which 🔥

fr fr check that return value, bestie — VDO_SUCCESS is the good ending, an error means something went sideways 😭
