From 5398dfb2592d525018997a991a4f7bfde515adc4 Mon Sep 17 00:00:00 2001 From: Florin Coras Date: Mon, 25 Jan 2021 20:31:27 -0800 Subject: session svm: non blocking mq Avoid synchronizing producers and the consumer. Instead, only use mutex or spinlock (if eventfds are configured) to synchronize producers.
