scsi_device_put(9)

✨ scsi_device_put ✨

okay so bestie, listen UP because this one's from the Kernel API Manual and it's literally the "letting go" era of scsi_device refcounting 💅

🌸 SYNOPSIS 🌸

void scsi_device_put (struct scsi_device *sdev );

🎀 ARGUMENTS 🎀

• sdev — the device you're releasing a reference on. that's the whole vibe. the target. the one you're saying bye to 🫶

💖 DESCRIPTION 💖

So what does it actually do, you ask? Okay so: it releases a reference to the scsi_device and decrements the use count of the underlying LLDD module — two things, one function call, no cap 🔥

And here's the iconic part: the device gets freed once the last user vanishes. Like, gone. Nobody's left holding a reference? The device is done for. main character final exit energy ✨

👑 ngl this is the "let it go" half of the refcount duo — every scsi_device_get needs its scsi_device_put or the device never gets freed and that's not the vibe you want (iykyk)
