From: Steve Dickson Date: Wed, 4 Mar 2009 20:22:37 +0000 (-0500) Subject: Only hash on IP address and Program number. Including the Procedure X-Git-Tag: nfs-utils-1-1-5~17 X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=681d340e682d95dd9fa6c120de2a24ddb155d581;p=nfs-utils.git Only hash on IP address and Program number. Including the Procedure number only creates needles extra hash entries.
