Nope, this only affects 32b apps on 64b systems. And it mostly breaks ASLR (see bug 1218800. This should be already in stable kernel branch -- You are receiving this mail because: You are the assignee for the bug.

I can see how this can over consume on thread's stacks because those are usually 2MB in size by default (by glibs) and the alignment would make it more likely THP target. I do not see THP would consume all the additional memory, though. Runtime overhead is likely a more likely visible effect. That being said. No objection to taking the patch from my end. -- You are receiving this mail because: You are the assignee for the bug.

Daniel has already mentioned that this might be THP related but only part of it can be contributed to that (135MB). So some userspace had to consume more memory with the newer kernel which is rather unexpected. Are you sure you are comparing the exactly same userspace here? -- You are receiving this mail because: You are the assignee for the bug.
