From f74b00d1dcf860db33eaeccc9afbf9daeec410e6 Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Thu, 5 Sep 2019 15:18:21 -0400 Subject: [PATCH] Maintain count of in flight requests for VQ_REQUEST queue As of now we maintain this count only for VQ_HIPRIO. Maintain it for VQ_REQUEST as well so that later it can be used to drain VQ_REQUEST queue.
