MFC r274337,r274673,274681,r275515:
ZFS large block support. The default recordsize remains at 128KB.
A new tunable/sysctl variable, vfs.zfs.max_recordsize is added to allow adjusting the permitted maximum record size, or zfs_max_recordsize, with a default of 1MB. ZFS will not allow setting recordsize greater than zfs_max_recordsize as a safety belt, because larger recordsize means greater read and write latency and more memory usage.
Please note that booting from datasets that have recordsize greater than 128KB is not supported (but it's Okay to enable the feature on the pool).
Limited safety belt is provided for mounted root filesystem but use caution when using a larger value.

MFC r271526: MFV r271510:
Enforce 4K as smallest indirect block size (previously the smallest indirect block size was 1K but that was never used).
This makes some space estimates more accurate and uses less memory for some data structures.
Illumos issue: 5141 zfs minimum indirect block size is 4K
