Description

As regression introduced in #6866 (and fixed in #8108) has shown, the behavior of fstat() on character special files is counter-intuitive - one needs to fopen() first, and then use stat() to find the st_size.

Currently, stat(2) tries to mention that, but it really could be improved:

       st_size
                     For regular files, this is the address of the end of the
                     file. For block special or character special, this is not
                     defined. See also pipe(2).
