From 0849e3ba53c3ef603dffa9758a73e07ed186a937 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Fri, 25 Jun 2010 12:22:09 +0900 Subject: TOMOYO: Add missing poll() hook. Commit 1dae08c "TOMOYO: Add interactive enforcing mode." forgot to register poll() hook. As a result, /usr/sbin/tomoyo-queryd was doing busy loop.
