atapi_eh_request_sense(9)

✨ NAME ✨

okay bestie, welcome to the atapi_eh_request_sense(9) page from the Kernel API Manual — the function is literally called atapi_eh_request_sense, and its whole job is perform ATAPI REQUEST_SENSE. That's the name, that's the vibe, periodt. 💅

🌸 SYNOPSIS 🌸

unsigned int atapi_eh_request_sense (struct ata_device *dev , u8
       *sense_buf , u8 dfl_sense_key );

🎀 ARGUMENTS 🎀

• dev — the device to perform REQUEST_SENSE to. Like, that's the target, bestie. 🎯
• sense_buf — result sense data buffer (SCSI_SENSE_BUFFERSIZE bytes long). Do not skimp on the buffer size, iykyk. 🫶
• dfl_sense_key — the default sense key to use. That's it, that's the assignment. ✨

🦋 DESCRIPTION 🦋

So here's the tea: this performs ATAPI REQUEST_SENSE after the device reported CHECK SENSE. This function is literally an EH helper. No cap. 💖

LOCKING: Kernel thread context (may sleep). So yeah, it may sleep — plan accordingly, bestie. 💅

🔥 RETURN 🔥

0 on success, AC_ERR_* mask on failure. Slay when it's zero, cry when it's the mask. 😭
