[RFC PATCH 0/2] sysctl: Panic on RCU stall and schedule while atomic
From: Daniel Bristot de Oliveira
Date: Tue May 31 2016 - 15:07:49 EST
This patch series implements two kernel.panic_on_* like sysctl:
kernel.panic_on_rcu_stall:
panic() on RCU Stall detection.
kernel.panic_on_sched_in_atomic:
panic() on schedule while atomic detection.
These sysctls are useful to capture a vmcore when is not possible
to recompile the kernel to include the panic() call. For instance
when supporting enterprise users.

rcu: sysctl: Panic on RCU Stall
sched: sysctl: Panic on scheduling while atomic
