[PATCH] inotify: fix event loss on hardlinked files
People have run into a problem when they do this: watch (file1, all_events); watch (file2, some_events); if file2 is a hard link to file1, some events will be missed because by default we replace the mask. The patch below adds a flag IN_MASK_ADD which will cause inotify to add to the existing mask if present.
