It means that if one processes is attempting directory creation and other
processes are performing other filesystem operations (including directory
creation, but not limited to it), then directory creation in the first process
is guaranteed to completely succeed (creating a directory with the desired path
and permissions and returning 0) or completely fail (returning an error and not
touching the file system). This is not the case on all file systems and on those
on which it is, the POSIX API does not guarantee that mkdir() is implemented to
take advantage of it.
