The patch adds an __attribute__((aligned(8))) to the

But there might be 32-bit applications out there which are using the
present wrong structure?
otoh, I assume that those applications would be using taskstats.h and would
hence encounter this bug and we would have heard about it, is that correct?
Yes, correct.
otoh^2, 32-bit applications running under 32-bit kernels will presently be
functioning correctly, and your change will require that those applications
be recompiled, I think?
Yes, correct. They would be broken with this fix. We could bump up the
version TASKSTATS_VERSION to 4. Would you like a new patch the version
bumped up?
I can do that.
Thanks
This patch looks like 2.6.20 and 2.6.21 material, but very carefully...
Yes, 2.6.20 and 2.6.21 sound correct.
OK. I guess we have little choice but to slam it in asap, with a 2.6.20.x backport
before too many people start using the old interface.
Thanks, again!
