Resending the entire series too often tends to split up the discussions between multiple threads, so should be used cautiously. My approach is that I don't resend the entire series except when all the patches have changed. And I only resend when the review round has reached a conclusion. While the review is ongoing doing incremental updates of the series is imo much better. But when resending the entire series, please start a new thread. Otherwise it again starts to become unclear which versions of which patches go together. And a quick aside if you fear that a patch causes subsequent patches to no longer apply without a rebase: I can deal with a lot of small conflicts quickly when merging. And if that doesn't cut it I'll just ask for a resend when needed. Just a quick reminder of patch resending bkms, intel-gfx is a really busy place so everyone needs to strive for best signal/noise ratio.
