vdo_decode_component_states(9)

💅 vdo_decode_component_states — Kernel API Manual (yes, the whole vibe) 🎀

okay so bestie, welcome to the Kernel API Manual entry for vdo_decode_component_states(9). grab a lil snack, this one's short but it's important. ✨

🌸 NAME 🌸

vdo_decode_component_states — literally just decode the payload of a super block. that's it. that's the whole job. 🫶

✨ SYNOPSIS ✨

int vdo_decode_component_states (u8 *buffer , struct volume_geometry
*geometry , struct vdo_component_states *states );

she takes three args and hands you back an int. iconic signature, no notes. 👑

🦋 ARGUMENTS 🦋

• buffer — the buffer holding the encoded super block contents. this is the raw tea, still in its wrapper. 🙈
• geometry — the vdo geometry. you know her, you love her. 💜
• states — a pointer that's gonna hold the decoded states. that's her lil home for the results. 🏠

🔥 RETURN 🔥

VDO_SUCCESS or an error. that's the whole spectrum, bestie — either slay or nope. 💀
