Subject: util: Make ovs_error() understand that EOF means "end of file".
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0fec26b00be202f828193a66ed35c842389588f4;p=openvswitch

util: Make ovs_error() understand that EOF means "end of file".

This convention is in use in a few places in the source tree, and so it
seems to be about time to start putting it into central places.
