Having one would be very useful, but there is no good mechanism to enumerate them (the best you can = do is grep for _IO(R|W)? in the system headers) and no way in general to tell = what the kernel will do with the parameter. --=20 You are receiving this mail because: You are the assignee for the bug.=
