The crash in question is a critical issue that we would want to have
a fix for soon. And while this is still being figured out, is it
okay to go with the fix I proposed in the V1 of this patch?
v6.10 has been released already, and it will be a couple months before
the v6.11 release.

It looks like the regression is 407d1a51921e, which appeared in v6.6,
almost a year ago, so it's fairly old.

What target are you thinking about for the V1 patch?  I guess if we
add it as a v6.11 post-merge window fix, it might get backported to
stable kernels before v6.11?  
Yes, I think we can go ahead with taking V1 patch for v6.11 post-merge window to
fix the current bug and ask Ubuntu to pick it while Lizhi's proposed patch goes
under test and review.

Thanks,
Amit
