sizeof returns the size of the char array buf[80] (standard C)
Looking at the code, I think Franck is right. buf is a "const unsigned char *" for which sizeof(buf) is the size of a pointer.
What kernel version are you looking at? I'm looking at 2.4.20 n_tty.c opost_block() and buf is a char array.
Oops, this should have been clarified sooner...
I was looking at a 2.6.11-rc2 tree I have hanging around here. So maybe the "buf" type was changed and the condition remained, and that produced the bug.
