✨ vdo_enqueue..._slab_waiter(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this is the vdo_enqueue_clean_slab_waiter page and honestly? it's short and it ate. let's get into it 🫶

🌸 NAME 🌸

vdo_enqueue_clean_slab_waiter — literally just: wait for a clean slab. that's it. that's the whole vibe check ✨

🦋 SYNOPSIS 🦋

int vdo_enqueue_clean_slab_waiter (struct block_allocator *allocator ,
struct vdo_waiter *waiter );

so you're calling this and it hands back an int, no cap. two args. iconic. 👑

💖 ARGUMENTS 💖

  • allocator — the block_allocator you're waiting on, like the main character of this whole situation.
  • waiter — the waiter itself. yes girl, that's the thing doing the waiting 🎀

⭐ RETURN ⭐

  • VDO_SUCCESS — slay, the waiter got queued 💅
  • VDO_NO_SPACE — there are literally no slabs to scrub, so like… nothing to do 😭
  • some other error — anything else, and it's giving unspecified chaos, ngl 💀
