SECURITYFS_REMOVE(9) Security Framework SECURITYFS_REMOVE(9)NAME
securityfs_remove - removes a file or directory from the securityfs filesystem
void securityfs_remove(struct dentry * dentry);
a pointer to a the dentry of the file or directory to be removed.
This function removes a file or directory in securityfs that was previously created with a call to another securityfs function (like
securityfs_create_file or variants thereof.)
This function is required to be called in order for the file to be removed. No automatic cleanup of files will happen when a module is
removed; you are responsible here.

debugfs_create_file - create a file in the debugfs filesystem
struct dentry * debugfs_create_file(const char * name, umode_t mode, struct dentry * parent, void * data,
const struct file_operations * fops);
a pointer to a string containing the name of the file to create.
the permission that the file should have.
a pointer to the parent dentry for this file. This should be a directory dentry if set. If this paramater is NULL, then the file will
be created in the root of the debugfs filesystem.
a pointer to something that the caller will want to get to later on. The inode.i_private pointer will point to this value on the open
a pointer to a struct file_operations that should be used for this file.
This is the basic "create a file" function for debugfs. It allows for a wide range of flexibility in creating a file, or a directory (if
you want to create a directory, the debugfs_create_dir function is recommended to be used instead.)
This function will return a pointer to a dentry if it succeeds. This pointer must be passed to the debugfs_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
If debugfs is not enabled in the kernel, the value -ENODEV will be returned.
