------------------- This is a commit scheduled for the next v2.6.34 longterm release. If you see a problem with using this for longterm, please comment. -------------------
commit e5b377a8fb7b05f27647698ac739a0504cb2bf80 upstream.
As it is, audit_syscall_entry() and secure_computing() get the bogus value (0, in fact)
