sci_port_rea...ational_exit(9)

💅 sci_port_ready_substate_operational_exit(9) — like, the exit era of the ready substate

okay bestie, sit down, grab a strawberry drink 🍓, because we're reading a Kernel API Manual page together and honestly? it's a short one but it ate. this is sci_port_ready_substate_operational_exit(9) and no, the title being all sci_port_rea...ational_exit(9) is not a typo on my end — that's just how the header renders it, truncated and mysterious, main character energy honestly 🎀

✨ NAME ✨

sci_port_ready_substate_operational_exit — and that's it. that's the whole name section. the original literally just drops the dash and walks away 💀 so no cute one-liner description for you, bestie. we move.

---

🌸 SYNOPSIS 🌸

void sci_port_ready_substate_operational_exit (struct
sci_base_state_machine *sm );

so it returns void (nothing, nada, she gives nothing back) and it takes exactly one thing: a struct sci_base_state_machine * named sm. periodt.

---

🦋 ARGUMENTS 🦋

• sm — okay so this is the object, and here's the little plot twist: it gets cast to a struct isci_port object. so like, on the surface she's a state machine but underneath she's an isci_port. iykyk 🧚

---

💖 DESCRIPTION 💖

so what does she actually do? this method performs the actions required by the struct isci_port when it's exiting SCI_PORT_SUB_OPERATIONAL. like, the port is leaving that substate and this function handles the goodbye chores. 💅

and the chores are, specifically:

• it reports the port as not ready
• it suspends the port task scheduler

that's the whole vibe check. also the original tacks a none on the end there, so. none. there it is. we're keeping it, don't @ me 😭

notice sci_port_resume_port_task_scheduler(9) sitting right there in the list while our girl suspends the scheduler? yeah. they're linked. the duality. 🌈

lowkey reminder bestie: this page is coming at you from ./drivers/scsi/isci and it's dated October 2026, so like, from the future apparently. time travel slay ⭐

and that's the page!! short, sweet, does her little job, suspends a scheduler, leaves. we stan a straightforward function 🫶💜
