I want to store some process-dependent information in my driver. I want to init them in open() and deinit them in flush(), these 2 methods get called when the app process calling open() or close() functions.
But if one parent process forked child process with my driver opened. Than, is the open() method get called? I want to store child-process-dependent as well. How about in dup() ?? Will the open() get called in this case? thanks.
