How to create a directory in user space in a Linux kernel module

Question

以下内容将在用户空间中创建文件，但是如何创建目录？

struct file *filp = filp_open("/home/myuser/Desktop/newfile", O_CREAT, S_IRWXU);

Answer 1

The best way I know how is to use:

mkdir("your/directory", 0700);

David Heffernan's comment shows the specifics.

Edit: This page will show you the different mode parameters you can give for your directory and what they do.

Answer 2

只需在filp_open标志中设置O_DIRECTORY 。
