chore(deps): bump userfaultfd 0.8.1→0.9.0 + repair duplicate-nix lock#27
Merged
Conversation
Supersedes dependabot #20 (conflicted after sha2/nix landed). userfaultfd 0.9 is API-compatible with the uffd snapshot-restore handler — cargo check --features firecracker passes. Also repairs Cargo.lock: the back-to-back dependabot merges (#19 nix, #21 sha2) left 'nix' specified twice in the lockfile, which fails 'cargo build' with a parse error on main. Regenerated the lockfile to dedupe it.
