Matthew Ahrens 2ac90457f5 record ioctl elapsed time in zpool history ... Each zfs ioctl that changes on-disk state (e.g. set property, create snapshot, destroy filesystem) is recorded in the zpool history, and is printed by `zpool history -i`. For performance diagnostic purposes, it would be useful to know how long each of these ioctls took to run. This commit adds that functionality, with a new `ZPOOL_HIST_ELAPSED_NS` member of the history nvlist. Additionally, the time recorded in this history log is currently the time that the history record is written to disk. But in many cases (CLI args logging and ioctl logging), this happens asynchronously, potentially many seconds after the operation completed. This commit changes the timestamp to reflect when the history event was created, rather than when it was written to disk.
