Subject: Re: [dts] [PATCH V2] disable ASLR for multi process test
Date: Tue, 27 Dec 2016 05:59:46 +0000 [thread overview]
Message-ID: <82F45D86ADE5454A95A89742C8D1410E3B4BD3E4@shsmsx102.ccr.corp.intel.com> (raw)

+ Yuanhan here for some comments on multi process test.
When test the application of multiprocess, do we need to disable ASLR? I am not sure if it's a point that we need to handle well in multi-process case.
