struct dentry * ntfs_get_dentry (struct super_block * sb, void * fh);
Find a dentry for the inode given a file handle sub-fragment. This function is called from fs/exportfs/expfs.c::find_exported_dentry which in turn is called from the default ->decode_fh which is export_decode_fh in the same file. The code is closely based on the default ->get_dentry helper fs/exportfs/expfs.c::get_object.
The fh contains two 32-bit unsigned values, the first one is the inode number and the second one is the inode generation.
Return the dentry on success or the error code on error (IS_ERR is true).
