Subject: (new_item, record_relation): Use `sizeof *var' rather
X-Git-Tag: v5.1.0~269
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0abb38e5874b51c6e33cdfe428021ea82425a3f9;p=thirdparty%2Fcoreutils.git

(new_item, record_relation): Use `sizeof *var' rather
than `sizeof EXPLICIT_TYPE'.
The former is more maintainable and usually shorter.
