[vbox-dev] vbox kernel modules cause hardlock on kernel 4.2.0-rc2

[Ramshankar]

Hi,

I believe this was the changeset that causes the change in caller 
assumption.

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/kernel/sched/core.c?id=1cde2930e15473cb4dd7e5a07d83e605a969bd6e

I need to figure out which exact kernel version was this changeset 
integrated into.

Regards,
Ram.
