Thanks for revising.

I've completely forgotten this changeset.

• Management to Interface

• sysctl -l to display the lenth of returned data.

• Bump the date, use "struct" as referenced in other parts of man sysctl, and give few examples of struct types.

Have you run mandoc -Tlint and igor on the manual page?

At the very least, the latter would hint that you need to bump .Dd :)

• Bump the date, use "struct" as referenced in other parts of man sysctl, and give few examples of struct types.

• Updated man page.

• systat: Added -F option to show "fmt"

• Update error description of show_info()

• Return error code from show_info()

I'm wondering if this change can be merged.
I have this change in local tree and haven't exposed to an issue since review was requested.

This looks like a useful change.

Do you want me to commit it?

I tested the new patch with 13.0-RELEASE and confirmed crash isn't happening.

I patched to 13.0-RELEASE.
I rebuilt and installed the new kernel to the specific machine.
I removed hint.agp.1.disabled="1" from /boot/loader.conf.
I verified the new kernel with the patch booted okay after removing the config.

I will test and report back.

There was a bug which resulted not calling new vm.objects_swap.
After fixing the bug and further testing, I no longer see long pause.
In other words, the kernel patch and new sysctl is helping performance improvement.

While you say that D31163 did not improve the performance issue with tmpfs files, did it improve performance on other tests? Or did it fail to improve performance on any of your tests?
