[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.
