10 days	test(memory): add coverage for mlock/mlock2/munlock/mlockall/munlockall	Paul Buetow
	The memory-locking cluster (FamilyMemory) had no end-to-end integration coverage; mmap_test.go only exercised mmap/msync/mremap/munmap. These syscalls return UNCLASSIFIED, so enter-tracepoint presence is the right end-to-end check (mlock/mlock2/munlock are KindMem, mlockall/munlockall are KindNull). Add a mmap-memory-lock scenario that, on a single anonymous page (small enough to stay under RLIMIT_MEMLOCK), issues raw syscalls for mlock, munlock, mlock2(addr,len,0), mlockall(MCL_CURRENT) and munlockall so the exact sys_enter_ tracepoints fire. mlock/mlock2/mlockall tolerate EPERM/ENOMEM best-effort since the enter tracepoint fires before the error; munlock/munlockall always succeed and clean up. TestMmapMemoryLock asserts enter_mlock, enter_munlock, enter_mlock2, enter_mlockall and enter_munlockall each fire (MinCount>=1, Comm ioworkload). All five captured under sudo.

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.
