Here is where the extra ADVLOCK happen:

Well, now it is. It took a long time to persuade the hardware guys
that manual cache coherence isn't workable.

IIUC ChewieFS follows FFS format, so the problem is block device driver.

We don't have exact plans just hope that it will be part of the kernel

It's a collection of code to make NetBSD loader easier. PLS look at
sys/lib/libsa/ directory. There are plenty of FS code. It's important

Hello. Are you seeing this behavior in NetBSD-5? I've been working
on porting ufs fixes from David Holland back into 5.x, and I've seen too
many unlocks taken on a given file, and have been wondering where they
come from. I'm not sure it's the same bug, but your finding sounds
