From 0c3dba1534569734ba353afdf3f11def497ff2ac Mon Sep 17 00:00:00 2001 From: John McCutchan Date: Thu, 4 Aug 2005 21:12:54 -0400 Subject: [PATCH] [PATCH] Clean up inotify delete race fix This avoids the whole #ifdef mess by just getting a copy of dentry->d_inode before d_delete is called - that makes the codepaths the same for the INOTIFY/DNOTIFY cases as for the regular no-notify case. I've been running this under a Gnome session for the last 10 minutes. Inotify is being used extensively.
