utime(2) and utimes(2) change a file's access/modification times by a real
filesystem path (filename at args[0]). The path was already captured
(KindPathname), but both syscalls fell through to FamilyMisc instead of
joining their siblings utimensat/futimesat in FamilyFS. Add them to
fsSyscalls and regenerate; the only generated change is trace IDs
1034-1037 flipping FamilyMisc -> FamilyFS.
Lock-in coverage:
- family_test.go asserts utime/utimes/utimensat/futimesat are all FamilyFS.
- classify_test.go + FormatUtime fixture assert utime is KindPathname with
PathnameField "filename" (path captured even though it is a char* string,
unlike domain/host name args).
- New ioworkload scenarios utime-basic/utimes/enoent and integration tests
TestUtimeBasic/Utimes/Enoent verify the path is captured at runtime,
including on the ENOENT error path.
Docs updated: moved utime/utimes from Misc to FS in
docs/syscall-tracing-plan.md to keep the drift tests green.
