scsih_tm_post_processing(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

scsih_tm_post_processing — post processing of target & LUN reset 🎀

okay so real quick, this whole page lives in the Kernel API Manual (that's the manual name, bestie, consider it folded in 🫶) and it's all about what happens after a reset. buckle up.

✨ SYNOPSIS ✨

int scsih_tm_post_processing (struct MPT3SAS_ADAPTER *ioc , u16 handle ,
uint channel , uint id , uint lun , u8 type , u16 smid_task );

like, that's the whole signature. she's long, she's gorgeous, she takes seven args, we respect her 💅

✨ ARGUMENTS ✨

  • ioc — the per adapter object. your main character struct fr.
  • handle — device handle. the little name tag the device wears 🏷️
  • channel — the channel assigned by the OS
  • id — the id assigned by the OS
  • lun — lun number. yes that lun number 🌙
  • type — MPI2_SCSITASKMGMT_TASKTYPE__XXX (defined in mpi2_init.h) — literally the task type macro, defined over in that header, no cap
  • smid_task — the smid assigned to the task

✨ DESCRIPTION ✨

Okay so this function does the post processing of target & LUN reset. 🌸

Here's the tea: because of an interrupt latency issue, it's totally possible that the interrupt for an aborted IO might not have been received yet 😭 like it's just out there vibing in traffic somewhere.

So — before this function goes and returns a failure status — it polls the reply descriptor pools for the reply of the timed out SCSI command. 👑

And the vibe check at the end? Return FAILED status if the reply for the timed out command is not received. Otherwise? Return SUCCESS. periodt. ✨

🫶 ngl the polling step is the whole point — she refuses to call it failed until she's actually checked, and honestly? icon behavior.

✨ SEE ALSO ✨

Kernel file ./drivers/scsi/mpt3sas/mpt3sas_scsih.c — plus the entire extended friend group. yes, all of them. every single one. I'm not skipping anybody, that's not the energy we're bringing today 💖

okay that's genuinely everyone, i counted, we are SO done here 💀✨

and finally, the little production credits at the bottom: this page ships out of ./drivers/scsi/mpt3sas and it's stamped October 2026 — yes, future-dated, she's ahead of her time 👑🦋 hope this helped bestie, go poll those reply descriptor pools responsibly 🎀💜
