The server silently ignores attempts to set the uid and gid on create.
Based on the comment, this appears to have been done to prevent some
overly-clever IRIX client from causing itself problems.
Perhaps we should remove that hack completely. For now, at least, it
makes sense to allow root (when no_root_squash is set) to set uid and
gid.
While we're there, since nfsd_create and nfsd_create_v3 share the same
logic, pull that out into a separate function. And spell out the
individual modifications of ia_valid instead of doing them both at once
inside a conditional.
Thanks to Roger Willcocks <roger@filmlight.ltd.uk> for the bug report
and original patch on which this is based.
