Subject: hmap: Fix bug in hmap_replace().
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9a757a721f675ceab5f0de2731c1de25f479f6c5;p=openvswitch

hmap: Fix bug in hmap_replace().

When hmap_replace() replaces one hash table node by another, it must
ensure that any nodes following the old node also follow the new node,
by copying the "next" pointer from "old" to "new".
