Thanks for the reference that does not involve looking at
CI log files. Filed away for future references.


Side note . . .

Turns out that tcptestsuite does not build for aarch64
do to alignment problems via packing in net/packetdrill :

Looks like I messed up and reported an armv7 context.
aarch64 built net/packetdrill and net/tcptestsuite just
fine. Sorry for the noise.

Re: Did something change with ZFS and vnode caching?

When I originally did this I thought that it made the most sense to
organize by the stack and then the lock name, but after staring at it
for a few hours, I decided that it might be more helpful to see it
aggregated by lock first and then stacks, so I switched it around:


Note that in order to reproduce these flame graphs, you'll have to
make a new version of Gregg's stackcollapse.pl that removes the weird
behavior the original version has for names with "->" in them,
as well as doing some additional postprocessing.

Users of opie will want to use this port and package...

https://cgit.freebsd.org/ports/tree/security/opie

Search lists for "opie" to find how volunteers could improve opie.
