It will now print more detailed information when a lock ordering was established through a chain of locks (e.g. lock1 is locked before lock2, lock2 is locked before lock3; therefore, locking lock3 before lock1 is a LOR). An example of the new output is in the review request ( https://reviews.freebsd.org/D54785). If you want to restore the old behavior, you can set the debug.witness.trace sysctl/tunable to 1. In the meantime, please let me know if you run into any trouble with the new functionality.

Hi Folks,

As a heads-up, I just committ= ed a change to the WITNESS output. It will now print more detailed informat= ion when a lock ordering was established through a chain of locks (e.g. loc= k1 is locked before lock2, lock2 is locked before lock3; therefore, locking= lock3 before lock1 is a LOR).

An example of the n= ew output is in the review request (https://reviews.freebsd.org/D54785).

I= f you want to restore the old behavior, you can set the=C2=A0debug.witness.= trace sysctl/tunable to 1.

In the meantime, please= let me know if you run into any trouble with the new functionality.
