From: John McCutchan Date: Fri, 5 Aug 2005 01:12:54 +0000 (-0400) Subject: [PATCH] Clean up inotify delete race fix X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0c3dba1534569734ba353afdf3f11def497ff2ac;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [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.
