Re: [PATCH] context_tracking: remove duplicate enabled check

Pull the check up to those functions, by making them simple wrappers around the user_enter and user_exit inline functions. With this and your other (not yet posted) patch, run time for the kvm-unit-tests vmexit.flat vmcall test with 10 million iterations drops from 17.8 to 17.5 seconds, which is about a 1.7% speedup. -- All rights reversed -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
