initialize_slab_scrubber(9)

💖 NAME 💖

Okay bestie, welcome to the initialize_slab_scrubber(9) page from the Kernel API Manual ✨. This function is the one that initializes an allocator's slab scrubber. That's literally its whole thing. Slay 💅.

✨ SYNOPSIS ✨

The signature is short and iconic:

int initialize_slab_scrubber (struct block_allocator *allocator );

🫶 ARGUMENTS 🫶

• allocator — the allocator being initialized. That's the one and only argument, and she's doing main-character work here 🎀.

🎀 RETURN 🎀

It returns VDO_SUCCESS or an error. No cap — either success or an error, periodt.
