The underlined statement is a gcc-way of assigning a function pointer. If
you notice struct file_operations you will find something similar to
int (*write)(args.....)
Normally you would assign this function pointer as
f_op->write = foo_write;
but gcc allows:
write: foo_write
So there is no need for providing the arguments.
HTH.
