💅 core_tmr_drain_state_list(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 🫶

---

✨ NAME ✨

core_tmr_drain_state_list — the function that aborts SCSI commands associated with a device. like, it goes in and clears out the outstanding commands tied to one specific device. no cap, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

void core_tmr_drain_state_list (struct se_device *dev , struct se_cmd
*prout_cmd , struct se_session *tmr_sess , bool tas , struct list_head
*preempt_and_abort_list );

it returns void, so don't go looking for a return value, she gives you nothing back and that's iconic of her honestly ✨

🎀 ARGUMENTS 🎀

• dev — the device for which to abort outstanding SCSI commands. this is the main character of the operation, everything is happening for this device 👑
• prout_cmd — pointer to the SCSI PREEMPT AND ABORT, but only if this function is called to realize the PREEMPT AND ABORT functionality. so it's a "depends on the situation" kind of pointer, iykyk 🦋
• tmr_sess — the session through which the LUN RESET has been received. like, who delivered the message 💌
• tas — the Task Aborted Status (TAS) bit from the SCSI control mode page. and because the original devs knew this needed context, here's the quote from SPC-4, paragraph "7.5.10 Control mode page", verbatim:

"A task aborted status (TAS) bit set to zero specifies that aborted commands shall be terminated by the device server without any response to the application client. A TAS bit set to one specifies that commands aborted by the actions of an I_T nexus other than the I_T nexus on which the command was received shall be completed with TASK ABORTED status."

ngl that's a whole paragraph but it matters, so read it fr fr 📖

• preempt_and_abort_list — for the PREEMPT AND ABORT functionality, a list with registrations that will be preempted. it's giving "guest list but make it hostile" 💀
