Revision eb61b5911bdc923875cde99eb25203a0e2b06d43 authored by Jamie Iles on 18 August 2017, 22:16:18 UTC, committed by Linus Torvalds on 18 August 2017, 22:32:02 UTC
When forcing a signal, SIGNAL_UNKILLABLE is removed to prevent recursive faults, but this is undesirable when tracing. For example, debugging an init process (whether global or namespace), hitting a breakpoint and SIGTRAP will force SIGTRAP and then remove SIGNAL_UNKILLABLE. Everything continues fine, but then once debugging has finished, the init process is left killable which is unlikely what the user expects, resulting in either an accidentally killed init or an init that stops reaping zombies.
