From 240a1853b4d2bce51e5cac9ba65cd646152ab6d6 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Fri, 15 Mar 2024 19:47:07 -0500 Subject: kernel: Remove signal hacks for vhost_tasks This removes the signal/coredump hacks added for vhost_tasks in: Commit f9010dbdce91 ("fork, vhost: Use CLONE_THREAD to fix freezer/ps regression") When that patch was added vhost_tasks did not handle SIGKILL and would try to ignore/clear the signal and continue on until the device's close function was called. In the previous patches vhost_tasks and the vhost drivers were converted to support SIGKILL by cleaning themselves up and exiting. The hacks are no longer needed so this removes them.
