Subject: [Qemu-devel] [PULL 26/36] replay: rename step-related variables and functions
Date: Tue, 20 Aug 2019 08:59:45 +0200	[thread overview]
Message-ID: <1566284395-30287-27-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1566284395-30287-1-git-send-email-pbonzini@redhat.com>

From: Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru>

This patch renames replay_get_current_step() and related variables
to make these names consistent with existing 'icount' command line
option and future record/replay hmp/qmp commands.
