       proc_dostring - read a string sysctl


       int proc_dostring  (ctl_table * table, int write, struct file * filp,
                            void __user * buffer, size_t * lenp,
                            loff_t * ppos);


       table  the sysctl table

       write   TRUE if this is a write to the sysctl file

       filp   the file structure

       buffer the user buffer

       lenp   the size of the user buffer

       ppos   file position


       Reads/writes  a  string  from/to  the user buffer. If the kernel buffer
       provided is not  large  enough  to  hold  the  string,  the  string  is
       truncated. The copied string is NULL-terminated. If the string is being
       read by the user process, it is copied and a newline ā€™\nā€™ is added.  It
       is truncated if the buffer is not large enough.

       Returns 0 on success.
