Kernel 3.13 not struct proc_dir_entry defined? Compile time always prompt error: dereferencing pointer to incomplete type, strives for the great god, the code is:

Mod_entry - & gt; The read_proc=proc_read;
Mod_entry - & gt; Write_proc=proc_write;
Printk (the KERN_INFO "% s module the loaded \ n", MODULE_NAME);
return 0;
}
Online some people say that such errors, because the header file contains is not complete, but I have to include the header file is put up, however, there is no use,,, a great god give directions, genuflect is begged the question already card for several days,,, break ChongXie!!!!!!!!!!
