- Bubbles, treemap, icicle, and the live flamegraph 'b' cycle now include
syscall duration (sum) as a third metric alongside events and bytes.
Statsengine snapshots expose TotalLatencyNs to support this.
- AttachAll takes an optional warn callback. Production passes one so older
kernels that lack newer tracepoints log a warning and keep going instead
of aborting startup.
- Dockerfile.el8 + scripts/build-with-docker-el8.sh + mage buildDockerEl8
produce ior.el8, a static binary built against Rocky Linux 8 glibc for
RHEL/Rocky/Alma 8 hosts.
- README.md documents installing mage and the new el8 target.
