From a0287db0f1d6918919203ba31fd7cda59bf889e8 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 8 Jan 2022 09:34:50 -0600 Subject: signal: Have prepare_signal detect coredumps using signal->core_state In preparation for removing the flag SIGNAL_GROUP_COREDUMP, change prepare_signal to test signal->core_state instead of the flag SIGNAL_GROUP_COREDUMP. Both fields are protected by siglock and both live in signal_struct so there are no real tradeoffs here, just a change to which field is being tested.
