Preparing 2.6.16-7, Call for discussion on SECCOMP and HZ_250



Hello,

I would like to schedule the upload of 2.6.16-7, containing 2.6.16.3 and
2.6.16.4, for tomorrow Apr. 13th.

Additionally, I would like to call for comments on the following options:

- SECCOMP: already deactivated in trunk, should be deactivated in sid
  too, for more info on the issue please see
  http://marc.theaimsgroup.com/?l=linux-kernel&m=113679955125413&w=2
  It seems to not change the ABI, so it could still be changed for -7.
  
- HZ_250 instead of HZ_1000: If I remember correctly, we kept HZ_1000 
  because it was the prior default. IMHO, we should follow upstream and 
  change the default to HZ_250 too. 

  A short pro/cons is here: http://kerneltrap.org/node/5411

  Considering we plan to use the smp-alternatives patches for both amd64
  and i386, at least here HZ_250 makes sense. For the other arches and
  flavours, either HZ_100 for smp and HZ_1000 for up/desktop flavours
  could make sense, or just HZ_250 too for the sake of simplicity.

  There will for sure be users requesting to revert this change, similar
  to PREEMPT, so I would like to have a concensus in the team regarding
  this option.


Best regards
Frederik Schueler
