target_stop_cmd_counter(9)

💅 target_stop_cmd_counter(9) — a Kernel API Manual moment

Okay so bestie, welcome to the kernel API manual, and specifically to target_stop_cmd_counter(9) — the tiny little function that hits the brakes. 🛑

---

✨ NAME ✨

target_stop_cmd_counter — stop new IO from being added to the counter.

Like, no new IO, bestie. The counter's closed for business. 💅

---

🌸 SYNOPSIS 🌸

void target_stop_cmd_counter (struct target_cmd_counter *cmd_cnt );

That's it. That's the whole signature. Void return, one pointer, absolutely no drama. 🫶

---

🎀 ARGUMENTS 🎀

• cmd_cnt — the counter to stop. Yep, that's the one you're shutting down. Hand it over and it stops accepting new IO. Iconic, honestly. ✨

---

🦋 SEE ALSO 🦋

Kernel file ./drivers/target/target_core_transport.c — that's where the magic lives, go look, iykyk. 👀

And the whole friend group, because this function does not exist in a vacuum:

• transport_init_session(9)
• transport_alloc_session(9)
• transport_alloc_session_tags(9)
• transport_init_session_tags(9)
• target_cmd_size_check(9)
• target_init_cmd(9)
• target_submit_prep(9)

• target_put_sess_cmd(9)
• target_stop_session(9)
• target_wait_for_cmds(9)
• target_wait_for_sess_cmds(9)
• transport_wait_for_tasks(9)
• translate_sense_reason(9)
• target_send_busy(9)

That's the whole squad, fr fr. 🌈

💀 Real talk though: this page is like three lines of docs and twenty lines of SEE ALSO. The main character energy is doing a lot of heavy lifting here. Not me complaining, just saying. 🙈

---

So that's the tea, bestie — target_stop_cmd_counter(9) stops new IO from being added to the counter, and that is genuinely all it does. Go forth and stop those counters. You're gonna slay. 👑

Signing off from ./drivers/target, dated October 2026, living in this Kernel API Manual era. 💖 Catch you in the next one! 🎀
