ata_msense_caching(9)

💅 ata_msense_caching(9) 💅

okay bestie, this page is from the Kernel API Manual, and it's literally about simulating a MODE SENSE caching info page. slay 💖

🌸 NAME 🌸

• ata_msense_caching — simulate a MODE SENSE caching info page ✨

🦋 SYNOPSIS 🦋

unsigned int ata_msense_caching (u16 *id , u8 *buf , bool changeable );

🎀 ARGUMENTS 🎀

• id — device IDENTIFY data 🫶
• buf — output buffer 💾
• changeable — whether changeable parameters are requested 👀

✨ DESCRIPTION ✨

So this one generates a caching info page, and that page conditionally indicates write caching to the SCSI layer, depending on device capabilities. it's giving "tell the SCSI layer what it needs to know, but only if the device can actually do the thing" 💅

LOCKING: None. no locks, no waiting, none of that — she's not holding anything 😌
