[RFC PATCH 22/24] pidfd: expose spawn builder system calls

From: Li Chen <hidden>
Date: 2026-07-16 14:45:34

Reply to: Li Chen, 2026-07-16

The preceding commits define the future-pidfd lifetime, configuration, and
run state machine without making them reachable from userspace. Each
preparatory step therefore remains bisectable without exposing a partial
process builder.

Make pidfd_open(0, PIDFD_EMPTY) create a taskless future pidfd and expose
pidfd_config() and pidfd_spawn_run(). Add the syscall declarations and
table entries together so the complete initial interface becomes reachable
at one commit boundary. Synchronize the lagging arm64 AArch32 perf mirror
through the current syscall table while adding the builder entries.
