Hello, I have a module which creates new device for data exchange between user program and a module. I was wondering, if I open the device in userspace and write() some piece of data to it, is it guaranteed that the driver will get this solid piece of data at once, or in certain circumstances it can be split into parts which are passed to the driver as several write events ?
