关于C#：在/ proc中写入文件会持续淹没dmesg

Writing a file in /proc continuouly floods the dmesg

我正在尝试使用/ proc文件输入工具在Linux内核模块中读取/写入变量。
内核模块编译成功，但是尝试通过

编写

1	echo 1 > My_file

此操作未完成。

此外，dmesg控制台会不断充斥一些随机值。

[ 1171.481271] proc_write_flag New_Flag 1124646486
[ 1171.481473] ^C

我是linux设备驱动程序的新手，正在尝试使用linux内核提供的/proc工具。我尝试删除此内核模块，但再次操作未完成。

是什么原因导致这种现象，我该如何纠正？

这是代码：
