Create a file with an initial size, the following function can be used
instead:
- struct dentry *debugfs_create_file_size(const char *name, umode_t mode,
- struct dentry *parent, void *data,
- const struct file_operations *fops,
- loff_t file_size);
+ void debugfs_create_file_size(const char *name, umode_t mode,
+ struct dentry *parent, void *data,
+ const struct file_operations *fops,
+ loff_t file_size);
file_size is the initial file size. The other parameters are the same
as the function debugfs_create_file.
