verify-fork-functions.sh flagged four functions present upstream but
absent here. Adapting to upstream per LOCAL-FORK-SUPREMACY-POLICY.md
Rule 2 (the fork must be complete) and Rule 3 (adapt, never pin back).
- redox_sys_call_multiple_v0 (src/platform/redox/libredox.rs). libredox
0.1.19 added 'call with multiple fds' and declares this symbol extern,
so relibc must export it or the multi-fd path fails to link. The fds
slice feeds 'impl Call for &[usize]', which the syscall fork already
provides. Upstream's no-payload arm calls a payload-less sys_call();
this fork keeps sys_call's payload parameter, so that arm passes an
empty payload rather than changing a signature every caller depends on.
- this_proc_call_ro / this_proc_call_wo (redox-rt/src/sys.rs). Upstream
split this_proc_call into a payload-less form plus these two. Added
alongside the fork's existing signature; both delegate to the fork's
sys_call_ro/sys_call_wo, whose signatures already match upstream.
- epoll_event::new (src/header/sys_epoll/mod.rs). Constructor that hides
whether the target layout carries the redox-only _pad field.
cargo check --target x86_64-unknown-redox passes.
