2026-06-06	test: add coverage for mknodat and ioprio_get/ioprio_set	Paul Buetow
	Add end-to-end integration scenarios and tests for two previously untested syscalls: - mknodat(2): new dir-mknodat-fifo scenario creates an unprivileged FIFO node (S_IFIFO, no CAP_MKNOD) via unix.Mknodat under AT_FDCWD and unlinks it. TestDirMknodatFifo asserts enter_mknodat fires with pathname@args[1] (after dirfd@args[0]), proven by a PathContains match on the distinct fifo name, mirroring the mkdirat coverage. - ioprio_get(2)/ioprio_set(2): new ioprio-basic scenario (the I/O-priority analogues of getpriority/setpriority) issues the raw syscalls (no x/sys wrapper exists), reading the current self I/O priority and re-applying it, or a harmless unprivileged best-effort value when none is set. TestIoprioBasic asserts enter_ioprio_get and enter_ioprio_set fire (null enters, UNCLASSIFIED ret), mirroring priority-basic. Realtime class is deliberately avoided as it needs CAP_SYS_ADMIN.

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.
