└─>Frame pointer unwinder
In linux kernel since version 3.10 (release Date: 2013-06-30)
This option enables the frame pointer unwinder for unwinding kernel
stack traces.
The unwinder itself is fast and it uses less RAM than the ORC
unwinder, but the kernel text size will grow by ~3% and the kernel's
overall performance will degrade by roughly 5-10%.
