Subject: [Qemu-devel] [PULL 28/36] icount: remove unnecessary gen_io_end calls
Date: Tue, 20 Aug 2019 08:59:47 +0200 [thread overview]
Message-ID: <1566284395-30287-29-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1566284395-30287-1-git-send-email-pbonzini@redhat.com>
From: Pavel Dovgalyuk <pavel.dovgaluk@gmail.com>
Prior patch resets can_do_io flag at the TB entry. Therefore there is no
need in resetting this flag at the end of the block.
This patch removes redundant gen_io_end calls.
