Addition to the inode number of fallthru/readdir, hardlink in union mount may be a problem. If you open a hardlinked file for writing or try chmod it, the internal copyup will happen and the hardlink will be destroyed. For instance, when fileA and fileB are hardlinked on the lower layer, and the contents of fileA is modifed (copyup happens). You will not see the latest contents via fileB. And the IN_CREATE event may be fired to the parent dir if you monitor it, I am afraid. (I have pointed out this issue before, but the posted document didn't seem to contain about it) J. R.
