| // static analysis. The Linux and OS X host mutexes are not |
| // necessarily annotated properly for this static analysis. As such, |
| // fs provides a macro that wraps the locking annotations, or noops |
| // when they are not present. This wrapping is exposed in the public |
| // fs interface as the locking requirements are part of public |
