	openat2(2) is the one open-family syscall with a structurally distinct argument layout: flags/mode live inside the open_how struct (args[2]), not as a plain int, and args[3] is the struct size. The tracer correctly reads the path from args[1] and omits flags (ev->flags = -1) rather than misreading the struct ptr/size, and registers the returned fd->path mapping via the shared handleOpenExit path. This was verified by inspection but had no integration scenario, unlike open/openat/creat/ open_by_handle_at. Add an open-openat2 ioworkload scenario issuing the raw openat2 syscall (Go has no wrapper and routes Open through openat) and a TestOpenOpenat2 integration test asserting the enter_openat2 tracepoint captures the path. Verified passing as root. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-04-24	task a8: move all binaries under ./cmd/<name>/main.go	Paul Buetow
	Relocates the two non-canonical main packages so every binary in the repo lives at ./cmd/<BINARY>/main.go: - tools/filewriter/ -> cmd/filewriter/ - integrationtests/cmd/ioworkload/ (20 files) -> cmd/ioworkload/ Consumers updated: - Magefile.go: workloadSourcePath now ./cmd/ioworkload - integrationtests/README.md: structure note points at ../cmd/ioworkload Files moved with git mv so git log --follow history is preserved. cmd/ior/main.go was already canonical and is untouched. Verified: mage build produces the ior binary; go build ./cmd/... builds filewriter and ioworkload; go test ./cmd/ioworkload passes; go vet ./cmd/filewriter ./cmd/ioworkload is clean.
