Porting Notes:
1. The unported "2932 support crash dumps to raidz, etc. pools"
caused a merge conflict due to a copyright difference in
module/zfs/vdev_raidz.c.
2. The unported "4128 disks in zpools never go away when pulled"
and additional Linux-specific changes caused merge conflicts in
module/zfs/vdev_disk.c.
