[v3,0/1] tcp/dcpp: Un-pin tw_timer

Message

Hi,

This is v3 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
=========

RFCv1 -> v2
++++++++

o Added comment in inet_twsk_deschedule_put() to highlight the race
o Added bh_disable patch

v2 -> v3
++++++++

o Dropped bh_disable patch
o Rebased against latest Linus' tree
