The lack of '.' and '..' entries hasn't caused any problems despite
cramfs/squashfs being used for a large number of years. I'm inclined
to believe any application that _relies_ on seeing '.' and '..'
returned by readdir is broken. This situation is easily fixed within
the application rather than forcing the filesystem to unnecessarily
fake '.' and '..' entries which are never used.

Yeah, let's fix every broken application on the planet instead of fixing
it in one place...

Fixing it in Squashfs implies Squashfs is broken. It isn't. If it has
to be "fixed" in the kenel, fix it in the VFS, it is after all the VFS
which makes '.' and '..' handling redundant in the filesystem.
