Peter A. Bigot	312f05eaef	subsys/fs: add implementation helper module File system API functions that operate on paths are passed both the absolute path including the mount point prefix, and the mount point within which the path lies. Unfortunately it's not entirely trivial to convert an arbitrary path within the file system space to an absolute path within its mount point, because the path may be to the mount point itself and not end with a directory separator. The effect is that a file system implementation like nffs may be given an empty path when "/" is required. Add an implementation module that does this transformation and use it to transform paths within each filesystem wrapper. Signed-off-by: Peter A. Bigot <pab@pabigot.com>	6 years ago

subsys/fs: add implementation helper module

File system API functions that operate on paths are passed both the
absolute path including the mount point prefix, and the mount point
within which the path lies.

Unfortunately it's not entirely trivial to convert an arbitrary path
within the file system space to an absolute path within its mount point,
because the path may be to the mount point itself and not end with a
directory separator.  The effect is that a file system implementation
like nffs may be given an empty path when "/" is required.

Add an implementation module that does this transformation and use it to
transform paths within each filesystem wrapper.
