And there are absolutely no changes I can see after -rc3 that would affect anything like this. No VFS layer changes that look at all likely, there are no ext4 changes at all, and the VM changes there are look rather unlikely too (ie they are about corner cases in page migration and transparent hugepage support - not to mention that it's almost certainly not some VM race or whatever if they are deterministic). The only unusual thing in Eric's setup is the mount namespace usage, but nothing has changed wrt that, at least since -rc3.
