securityfs_create_dir(9) create a directory in the securityfs filesystem


struct dentry * securityfs_create_dir(const char * name, struct dentry * parent);



a pointer to a string containing the name of the directory to create.


a pointer to the parent dentry for this file. This should be a directory dentry if set. If this parameter is NULL, then the directory will be created in the root of the securityfs filesystem.


This function creates a directory in securityfs with the given name.

This function returns a pointer to a dentry if it succeeds. This pointer must be passed to the securityfs_remove function when the file is to be removed (no automatic cleanup happens if your module is unloaded, you are responsible here). If an error occurs, NULL will be returned.

If securityfs is not enabled in the kernel, the value -ENODEV is returned. It is not wise to check for this value, but rather, check for NULL or !NULL instead as to eliminate the need for #ifdef in the calling code.
