Hi! I see this in virtio_ring.c: /* Put entry in available array (but don't update avail->idx * until they do sync). */ Why is it done this way?

Hello, My question is about which Linux distribution to choose for Asterisk. (/me holds breath) OK, hopefully you're still reading, because whatever you were thinking now, you're thinking wrong! ;) First of all, I want to make clear that I have read EVERY message and reply that I could possibly find about this topic, so that includes the dozens of messages here on the Asterisk
