struct file* alloc_file ( struct path *  path, fmode_t  mode, const struct file_operations *  fop  )

read

alloc_file - allocate and initialize a 'struct file' : the vfsmount on which the file will reside : the dentry representing the new file : the mode with which the new file will be opened : the 'struct file_operations' for the new file

Use this instead of get_empty_filp() to get a new 'struct file'. Do so because of the same initialization pitfalls reasons listed for init_file(). This is a preferred interface to using init_file().

If all the callers of init_file() are eliminated, its code should be moved into this function.
