🎀 ufshcd_pause_command_processing(9) — Kernel API Manual 🎀

✨ NAME ✨

ufshcd_pause_command_processing — Pause command processing. That's the whole name vibe, no cap. 💖

---

🌸 SYNOPSIS 🌸

Here's the signature, bestie — copy it exact:

int ufshcd_pause_command_processing (struct ufs_hba *hba , u64
timeout_us );

---

🦋 ARGUMENTS 🦋

• hba — the per-adapter instance, aka the main character of this little UFS story 💅
• timeout_us — timeout in microseconds to wait for pending commands to finish, so basically the "how long are we waiting for everyone to wrap it up" number ⏰

---

💖 DESCRIPTION 💖

Okay so this function is the "no new submissions" button: it stops new command submissions and waits for existing commands to complete. Very "everybody chill while the current commands finish" energy. ✨

---

🔥 RETURN 🔥

• 0 — success, slay ✅
• -EBUSY — commands did not finish within timeout_us; that's the busy signal 😭

On failure, all acquired locks are released and the tagset is unquiesced. So the cleanup is part of the deal — no cap. 🫶
