oldstat and friends

oldstat and friends

[Ameer Armaly]

Hi all.  I was reading in to some of the fs code, and I've found out that 
oldstat and friends have been deprecated since linux 2.0.  Is there any 
reason why these calls should not be removed outright or are there cases 
where they are still needed?

We can still run binaries from 1991 or thereabouts.  Removing oldstat
would break that ability.

We should probably make those symbols conditional on CONFIG_BINFMT_AOUT
or introduce a new CONFIG_COMPAT_ANCIENT flag or something.

Why are you keen to remove it?  It doesn't cost many bytes of kernel
image.

Nothing in particular, just seeing what can be cleaned out for purposes of 
cleaning out.
