sd_revalidate_disk(9)

💅 sd_revalidate_disk(9) — Kernel API Manual ✨

okay so bestie, we're looking at sd_revalidate_disk from the kernel API manual and honestly? this one's kind of a big deal. it's the function that gets called the first time a new disk is seen — like the disk's lil debut moment 🎀 — and it does all the getting-to-know-you stuff: disk spin up, read_capacity, etc. main character energy fr fr.

✨ SYNOPSIS ✨

void sd_revalidate_disk (struct gendisk *disk );

like, that's the whole signature. no cap. 🦋

🌸 ARGUMENTS 🌸
