2600990e Ralf Baechle 2006-04-05 1090 ret = getcwd(v->cwd, VPE_PATH_MAX);
When examining the code to see what v->uid and v->gid were used for I
discovered that the only users in the kernel are vpe_getuid and
vpe_getgid, and that vpe_getuid and vpe_getgid are never called.
So instead of proposing a conversion to use kuid_t and kgid_t instead
of unsigned int/int as I normally would let's just kill this dead code
so no one has to worry about it further.

This is a good catch. vpe_get[u|g]id was originally used by KSPD which
has been removed.
