From e42e27736de80045f925564ea27a1d32957219e7 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Thu, 11 Jun 2009 11:09:47 -0400 Subject: inotify/dnotify: should_send_event shouldn't match on FS_EVENT_ON_CHILD inotify and dnotify will both indicate that they want any event which came from a child inode. The fix is to mask off FS_EVENT_ON_CHILD when deciding if inotify or dnotify is interested in a given event.
