there's no "backtrace sysctl" planned for the moment. This "hung tasks"
debugging feature can be disabled/enabled on a wide scale already:
- in the .config
- runtime, temporarily, via:
echo 0 > /proc/sys/kernel/hung_task_timeout_secs
- runtime, permanently, via adding:
kernel.hung_task_timeout_secs = 0
to /etc/sysctl.conf.
the backtrace, as other posters have stated it in this thread too, is
very useful, so i'll not remove it from the printout.
