💅 apply_new_vdo_configuration(9) — like, the Kernel API Manual page you actually wanna read 🎀

okay bestie, so this one lives in the Kernel API Manual (yes, apply_new_vdo_configuration(9), section 9, kernel-land, very serious business) and honestly? it's lowkey a little guy with a big job. let's get into it ✨

🌸 NAME 🌸

apply_new_vdo_configuration — the function that attempts to make any configuration changes from the table being resumed. that's it, that's the whole vibe. it tries. it attempts. it's giving "i'll do my best" energy 🫶

✨ SYNOPSIS ✨

int apply_new_vdo_configuration (struct vdo *vdo , struct device_config
*config );

look at that signature. two pointers, one int return. iconic. no cap 🎀

🦋 ARGUMENTS 🦋

  • vdo — the vdo being resumed. that's the main character right there 👑
  • config — the new device configuration, and it's derived from the table with which the vdo is being resumed. so like, it came from the table, bestie. it's a whole derivative situation 💅

🔥 RETURN 🔥

VDO_SUCCESS or an error. that's the whole spectrum — flawless victory or an error, no in-between, no "it's complicated" 😭

ngl, "or an error" is doing a lot of heavy lifting in that sentence but we respect it fr fr
