ata_mselect_caching(9)

💖 NAME 💖

ata_mselect_caching(9) — okay bestie, this is the Kernel API Manual page for the function that simulates MODE SELECT for the caching info page. It’s giving kernel-internals realness and I’m obsessed 💅✨

---

✨ SYNOPSIS ✨

       int ata_mselect_caching (struct ata_queued_cmd *qc , const u8 *buf , int
       len , u16 *fp );

---

🎀 ARGUMENTS 🎀

• qc — storage for the translated ATA taskfile, bestie 🫶
• buf — the input buffer
• len — number of valid bytes in the input buffer
• fp — out parameter for the failed field on error

---

🦋 DESCRIPTION 🌸

Okay so this one prepares a taskfile to modify caching information for the device. That’s the whole plot, no cap 💖

LOCKING: None. Literally none. No locks here, bestie 😭

💅 SEE ALSO 💅

Kernel file ./drivers/ata/libata-scsi.c — that’s where the magic lives ✨
