It should be the same 4096.

The test environment can be slightly different, I used a larger guest this time
(20G, 40 cores), though.  Previously it should be a few gig only with a few 
cores.

Side note: would you also consider picking up this patch along with the series?

https://lore.kernel.org/qemu-devel/20211130080028.6474-1-peterx@redhat.com/

I wanted to make sure it lands before this series, e.g., when enabled both
dirty limit and migration, disabling dirty limit might trigger the bug already.

Thanks,
