Users of pseudofs (e.g. lindebugfs), should be able to receive input from command line via commands like "echo 1 > /path/to/file". Currently this fails because sh tries to truncate the file first and vop_setattr returns not supported error for this. This patch simply ignores the error and returns 0 instead.
