vm_fault_t(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… NAME πŸ’…

okay bestie so this is vm_fault_t(9) from the Kernel API Manual, and the whole entire vibe is: typedef vm_fault_t β€” the return type for page fault handlers. that's it, that's the icon. πŸŽ€


✨ Description ✨

so like. when a page fault handler finishes doing its little thing, it doesn't just return 0 or 1 like some basic function β€” no ma'am. it returns a bitmask of VM_FAULT values. 🫢

that's the whole paragraph. slay, honestly.

ngl the word "bitmask" is doing a lot of heavy lifting here β€” it's giving flags energy, it's giving "many booleans in a trench coat" energy. πŸ”₯
