From 3de0ef4f2067da58fa5126d821a56dcb98cdb565 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 14 Oct 2009 20:54:03 +0800 Subject: inotify: fix coalesce duplicate events into a single event in special case If we do rename a dir entry, like this: rename("/tmp/ino7UrgoJ.rename1", "/tmp/ino7UrgoJ.rename2") rename("/tmp/ino7UrgoJ.rename2", "/tmp/ino7UrgoJ") The duplicate events should be coalesced into a single event. But those two events do not be coalesced into a single event, due to some bad check in event_compare(). It can not match the two NULL inodes as the same event.
