Paul Dagnelie 17e212652d Prevent zevent list from consuming all of kernel memory ... There are a couple changes included here. The first is to introduce a cap on the size the ZED will grow the zevent list to. One million entries is more than enough for most use cases, and if you are overflowing that value, the problem needs to be addressed another way. The value is also tunable, for those who want the limit to be higher or lower. The other change is to add a kernel module parameter that allows snapshot creation/deletion to be exempted from the history logging; for most workloads, having these things logged is valuable, but for some workloads it produces large quantities of log spam and isn't especially helpful.
