Subject: [PATCH] RISC-V: KVM: Exit run-loop immediately if xfer_to_guest fails
Date: Tue, 8 Nov 2022 17:25:43 +0530 [thread overview]
Message-ID: <20221108115543.1425199-1-apatel@ventanamicro.com> (raw)
If xfer_to_guest_mode_handle_work() fails in the run-loop then exit
the run-loop immediately instead of doing it after some more work.
