From e338c4c2b620ba4e75fd3576f8142eb93be12ce3 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Tue, 25 Nov 2014 08:20:05 +0100 Subject: drm/vmwgfx: Fix error printout on signals pending The function vmw_master_check() might return -ERESTARTSYS if there is a signal pending, indicating that the IOCTL should be rerun, potentially from user-space. At that point we shouldn't print out an error message since that is not an error condition. In short, avoid bloating the kernel log when a process refuses to die on SIGTERM.
