From 5a816b92a328070ecaa3d0251baea14b9bf906c4 Mon Sep 17 00:00:00 2001 From: Rick Macklem Date: Wed, 4 May 2011 22:02:33 +0000 Subject: [PATCH] Add a comment noting that the NFS code assumes that the values of error numbers in sys/errno.h will be the same as the ones specified by the NFS RFCs and that the code needs to be fixed if error numbers are changed in sys/errno.h.
