πŸ’… vdo_initialize_component_states(9) πŸ’…

okay so bestie, welcome to the Kernel API Manual ✨ this one lives in the kernel source tree at ./drivers/md/dm-vdo, and it's fr fr one of those little functions that does exactly what its name says. no cap. 🫢


✨ NAME ✨

vdo_initialize_component_states β€” initializes the components so they can be written out πŸ’– like, it's getting the whole squad dressed and ready to be photographed, y'know?


πŸ¦‹ SYNOPSIS πŸ¦‹

int vdo_initialize_component_states (const struct vdo_config *vdo_config
, const struct volume_geometry *geometry , nonce_t nonce , struct
vdo_component_states *states );

look at that signature. iconic. returns an int, takes four things, she's booked and busy πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • vdo_config β€” the config used for component state initialization. this is the blueprint, the vibe check for how everything should be set up πŸ’œ
  • geometry β€” the volume geometry used to calculate the data region offset. she's the one who knows where things go πŸ¦‹
  • nonce β€” the nonce to use to identify the vdo. yes, like a little name tag for your vdo so you know it's yours πŸ™ˆ
  • states β€” the component states to initialize. this is the glow-up target β€” you hand it over and it comes back ready to be written out ✨

⭐ RETURN ⭐

VDO_SUCCESS or an error code. that's it, that's the tea πŸ“ either she ate or she didn't, no in-between.

like half the dm-vdo subsystem is in here. read them all. i'm so serious. 🧚
