From 5a64e9425160ace607b2043804d73d5579808bd3 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Wed, 25 May 2016 21:48:47 -0600 Subject: qcow2: add tracepoints for qcow2_co_write_zeroes This patch follows guidelines of all other tracepoints in qcow2, like ones in qcow2_co_writev. I think that they should dump values in the same quantities or be changed all together. Signed-off-by: Denis V.
