From e234f35c54a30d040313e40833dcf623d14629b4 Mon Sep 17 00:00:00 2001 From: John McCutchan Date: Thu, 4 Aug 2005 13:07:08 -0700 Subject: [PATCH] inotify delete race fix The included patch fixes a problem where a inotify client would receive a delete event before the file was actually deleted. The bug affects both dnotify & inotify.
