security: remove security_sb_post_mountroot hook
The security_sb_post_mountroot() hook is long-since obsolete, and is fundamentally broken: it is never invoked if someone uses initramfs. This is particularly damaging, because the existence of this hook has been used as motivation for not using initramfs. Stephen Smalley confirmed on 2007-07-19 that this hook was originally used by SELinux but can now be safely removed: http://marc.info/?l=linux-kernel&m=118485683612916&w=2 Cc: Stephen Smalley <sds@tycho.nsa.gov> Cc: James Morris <jmorris@namei.org> Cc: Eric Paris <eparis@parisplace.org> Cc: Chris Wright <chrisw@sous-sol.org> Signed-off-by: H.
