scsi_device_is_pseudo_dev(9)

💅 scsi_device_is_pseudo_dev ✨

Okay so bestie, welcome to the scsi_device_is_pseudo_dev(9) page — this is from the Kernel API Manual, and it's literally a whole vibe check for SCSI devices 🦋

🎀 SYNOPSIS 🎀

bool scsi_device_is_pseudo_dev (struct scsi_device *sdev );

🌸 ARGUMENTS 🌸

• sdev — the SCSI device you want to examine, bestie. Like, this is the one you're putting under the microscope 🔍

✨ DESCRIPTION ✨

So here's the tea ☕ — a pseudo SCSI device can be used to allocate SCSI commands, but it does not show up in sysfs. Ngl, it's kind of giving invisible main character energy 💀

Also, heads up: the logical unit information in *sdev is made up. Fake. Fabricated. Not real. 🙈

This function tests the LUN number instead of comparing sdev with sdev->host->pseudo_sdev, because — plot twist — this function may be called before sdev->host->pseudo_sdev has been initialized. So yeah, it can't do the comparison, it's not available yet, periodt 💅
