ENUM SCI_IO_STATUS(9)

💖 NAME 💖

okay so bestie, this is enum sci_io_status(9) from the Kernel API Manual ✨ and it’s the enum that holds all the possible IO completion status values. The way that every value in this enumeration maps directly 1:1 to a value in the enum sci_status enumeration is lowkey iconic — so if you want the detailed comments about what a status actually represents, please refer to that enumeration. Periodt 💅

🌸 Description 🌸

The Description section is giving “add this API” todo-note energy, ngl: it says to add the API that retrieves the SCU status from the core 🫡 Then it says to check that the following status are properly handled — and yes, both items are coming at you exactly:

• SCI_IO_FAILURE_UNSUPPORTED_PROTOCOL
• SCI_IO_FAILURE_INVALID_IO_TAG

🔥 SEE ALSO 🔥

• Kernel file ./drivers/scsi/isci/isci.h; enum sci_status(9), enum sci_task_status(9), sci_swab32_cpy(9) — the whole reference squad, fr fr 🫶 iykyk

cute sign-off: this page came from the source/version ./drivers/scsi/isci, dated October 2026, and its title is enum sci_io_status(9) 💖 May your IO completions be SCI_IO_SUCCESS and your vibes be immaculate 🌈✨
