From 3569cb7b789cf39273cad7c902d8f2685ebf011c Mon Sep 17 00:00:00 2001 From: Alexander Ivanov Date: Mon, 24 Apr 2023 11:31:40 +0200 Subject: [PATCH] parallels: Use generic infrastructure for BAT writing in parallels_co_check() BAT is written in the context of conventional operations over the image inside bdrv_co_flush() when it calls parallels_co_flush_to_os() callback. Thus we should not modify BAT array directly, but call parallels_set_bat_entry() helper and bdrv_co_flush() further on. After that there is no need to manually write BAT and track its modification. This makes code more generic and allows to split parallels_set_bat_entry() for independent pieces. Signed-off-by: Alexander Ivanov Reviewed-by: Denis V.
