Will do if necessary, but hmm, I heard from KAMEZAWA-san that he has already sent some patches to fix the similar problems on RHEL6, and I prefer his fixes to mine. Should I(or KAMEZAWA-san?) forward port his patches onto current aa.git ? > There's some slight > difference in the code here and there that makes the fixes not so > portable across releases (uncharge as param of move_account which > wasn't there before as an example...). > Agreed. And I think you'll see some extra changes of memcg in 2.6.36... Any way, I'll do some test in both RHEL6 and aa.git when I have a time, and feel free to tell me if you have any troubles in back/forward porting memcg's fixes.
