// Much filesystem code is built both for Fuchsia and for Linux or OS
// X hosts. This includes code instrumented with Clang's locking
// 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
// interfaces.
