kstat: desire type for timestamps
occasionally a real time (64-bit hrtime?) is useful, and it would be nice to express this in kstats. We have snaptime and crtime already, so adding a discrete kstat type would be useful. (For example, I want to record the time when a configuration changed, or the time when a device was reset.) I could print this using strings, but using a 64-bit integer would be much more efficient, and avoid trying to do hard time calculations in the kernel.
I'm thinking KSTAT_TYPE_TIMESTAMP
If folks agree, I'll prepare a changeset for this.
