I was able to reproduce crash on 5.15.y kernel during COW, and
when the grandchild process attempts a write to a private page
inherited from the child process and the private page contains
a memory uncorrectable error. The way to reproduce is described
in Tony's patch, using his ras-tools/einj_mem_uc.
And the patch series fixed the panic issue in 5.15.y.
But you are skipping 6.1.y, which is not ok as it would cause
regressions when you upgrade.
I'll drop this from my review queue now, please provide working
backports for this and newer releases, and I'll be glad to take them.
Thanks for the guidance, will do.
To confirm, you're looking for backport to both 6.1.y and 5.15.y, and
nothing else, correct? Just curious, why 6.1.y in particular?
If you don't think it needs to go to any kernels older than 5.15.y, that would
be fine.
And as for 6.1.y, look at the front page of www.kernel.org, it shows the
active kernel versions. We can't apply a change to an older kernel tree
only because if you upgrade to a newer one (i.e. from 5.15.y to 6.1.y),
you would have a regression which we don't ever want.
Got it, thanks!
