ok, i've bisected it, and the bad commit is:

3dc43e3e4d0b52197d3205214fe8f162f9e0c334 is the first bad commit
commit 3dc43e3e4d0b52197d3205214fe8f162f9e0c334

per-netns ipv4 sysctl_tcp_mem

This patch allows each namespace to independently set up
its levels for tcp memory pressure thresholds. This patch
alone does not buy much: we need to make this values
per group of process somehow. This is achieved in the
patches that follows in this patchset.
