From 442fde405d86c555ac09994772c85ca15a3b4fc7 Mon Sep 17 00:00:00 2001 From: Dean Deng Date: Thu, 30 Apr 2020 09:46:36 -0700 Subject: Fix proc net bugs in VFS2. The /proc/net/udp header was missing, and /proc/sys/net was set up as /proc/sys/net/net. Discovered while trying to run networking tests for VFS2.
