In fact, it is already used on many locations in seq_buf.c. Or we might want to get rid of "unsigned char" in seq_buf.c here as well. > + size_t size; > + size_t len; > + loff_t readpos; I have just noticed that the variable is called "read_pos" in seq_file. Are you going to sync the name later? Also I am a bit curious that "readpos" use another type than "len" and "size". Well, this is not in the scope of this patchset. I am fine with keeping "loff_t" at this point.
