spi_dv_device(9)

💅 spi_dv_device(9) 💅

okay so bestie, welcome to the Kernel API Manual page for spi_dv_device(9) — yes, the 9 is part of the name, we love a section-number moment 💖.

✨ NAME ✨

spi_dv_device — Do Domain Validation on the device 💅

🌸 SYNOPSIS 🌸

void spi_dv_device (struct scsi_device *sdev );

🎀 ARGUMENTS 🎀

• sdev — the scsi device to validate. That's the whole argument, and she is literally the main character of this function call 🫶.

🦋 DESCRIPTION 🦋

Okay so here's the vibe: spi_dv_device performs the domain validation on the given device, and it does it in the current execution thread — no sneaky background-thread handoff, bestie ✨.

Because DV operations may sleep, the current thread must have user context. Like, fr fr, this is a requirement, not a suggestion 😭.

Also: no SCSI related locks that would deadlock I/O issued by the DV may be held. Translation? Do not be holding SCSI related locks that would deadlock the I/O issued by the DV — that would be giving deadlock, and we are not giving deadlock 💀.

🚨 Bestie warning: the current thread must have user context, and no SCSI related locks that would deadlock I/O issued by the DV may be held. Keep that vibe check clean, okay? 🙈
