From ef9c5160a18f4d0eee3cbd878fab766b22797269 Mon Sep 17 00:00:00 2001 From: Peter Lieven Date: Thu, 8 Mar 2018 12:18:26 +0100 Subject: [PATCH] migration/block: rename MAX_INFLIGHT_IO to MAX_IO_BUFFERS this actually limits (as the original commit mesage suggests) the number of I/O buffers that can be allocated and not the number of parallel (inflight) I/O requests.
