## Summary 1. fs/reference_count: set default reference count option to n Most of developers will not have the scenarios of open/close file descriptors in multi-threads, The default option will incur additional code size overhead for such devices. this PR will preserve the behavior before PR#13296 was introduced, and ensure that the default code size is not affected. Note that this option will ensure the safety of access to the file system from multi-tasks (Task A blocking rw(fd), then Task B close(fd)), the disadvantage is that it will increase the amount of code-size, there is no need to enable this option if the application could ensure he file operations are safe. 2. sched/timer: move sigev_notify_thread_id to SIG_EVTHREAD Some developers do not need this kind of advanced features, move sigev_notify_thread_id into SIG_EVTHREAD to save the code size. 3.
