From c05594b62125c528d93af3a78229793aae36df7f Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Mon, 13 Jul 2009 15:56:55 -0400 Subject: [PATCH] fsnotify: fix inotify tail drop check with path entries fsnotify drops new events when they are the same as the tail event on the queue to be sent to userspace. The problem is that if the event comes with a path we forget to break out of the switch statement and fall into the code path which matches on events that do not have any type of file backed information (things like IN_UNMOUNT and IN_Q_OVERFLOW). The problem is that this code thinks all such events should be dropped. Fix is to add a break.
