Hi,

Below are the kernel messages for the overhead and schedule tracers.

When I'm looking for UNLOCK events through ftdump, I noticed that almost
all UNLOCK_START records are generated with IRQ enabled for both protocols
I'm running. Is this why these records are not being counted? Is there any
parameter so I can collect these records?
