So, if run current version of fsck.overlay on overlayfs which was mounted with index=on or nfs_export=on, if cannot guarantee the relationship between dirs/files in indexdir and upper dir, so may lead to inconsistency in indexdir. This drawback will be addressed through introduce overlay feature set as Amir suggested, I will post it soon and maybe write a NOTE or BUG in README is better before everything is done. > I know some advanced features are only implemented in high > kernel version, I just want to make sure if the common check > and repair functions are available for 4.4 kernel?
