From a274f6ff3c5c79c27d254b48cad3b4814c950908 Mon Sep 17 00:00:00 2001 From: Arseniy Krasnov Date: Fri, 19 Aug 2022 05:31:43 +0000 Subject: vmci/vsock: use 'target' in notify_poll_in callback This callback controls setting of POLLIN, POLLRDNORM output bits of poll() syscall, but in some cases, it is incorrectly to set it, when socket has at least 1 bytes of available data. Use 'target' which is already exists.
