I didn't know how to get hold of a "struct pt_regs*" till someone sent me a
message this morning (it was obvious really). Plus, it occurred to me that I
already have this fd I can use for reference counting.

Because "getting" the struct file from the fd increments the usage count on
the struct file. The VFS automatically maintains the module count pointed to
by the file_operations structure based on the existence of the struct file.
