Hi,
This is v4 of the series where the tw_timer is un-pinned to get rid of interferences in isolated CPUs setups.
Eric mentionned rsk_timer needs looking into, but I haven't had the time to do that. It doesn't show up in our testing, which might be due to its relatively low timeout (IIUC 3s).
Revisions =========
v3 -> v2 ++++++++
o Rebased against latest Linus' tree o Added ehash lock usage to serialize scheduling vs descheduling of the tw_timer (Paolo)
v2 -> v3 ++++++++
o Dropped bh_disable patch o Rebased against latest Linus' tree
RFCv1 -> v2 ++++++++
o Added comment in inet_twsk_deschedule_put() to highlight the race o Added bh_disable patch
