It is not necessary, but otherwise you have to write something similar on your own.

Necessary is the rtems_bdbuf_purge() function which should be available in 4.10.

You have to be extremely careful when you unmount.  The file system must have 
no open nodes (chroot() and chdir() are particular problematic) and there must 
be no node evaluation process in progress.

It is the CVS head.
