Shared Memory File System
=========================
Include support for shm_open() and shm_close.
This supports the POSIX shm_open() APIs for shared memory among unrelated
apps.
It can be enabled with ``CONFIG_FS_SHMFS=y``. To check how it works, please
also enable the example app via ``CONFIG_EXMAPLE_SHM=y`` and run ``shm_test``
from NSH command line.
This file system doesn't support mount operations though.
If comment the line using ``shm_unlink()`` in the example app, we can see
a file under ``/var/shm/`` from NSH command line after running the example.
We can also remove that file from command line.
