This series is an RFC, it outlines how an filesystem, in this case UBIFS, could implement a mount option to disable filesystem operations on encrypted files where no key is present. The desired byproduct is that in this case ->d_revalidate() is not needed anymore and VFS folks are in less fear about the dcache implications.
