* Add libzutil for libzfs or libzpool consumersDon Brady2018-11-051-100/+55
| | | | | | | | | | | Adds a libzutil for utility functions that are common to libzfs and libzpool consumers (most of what was in libzfs_import.c). This removes the need for utilities to link against both libzpool and libzfs.

* Pool allocation classesDon Brady2018-09-051-7/+16
| | | | | | | | | | | | | | | | | | | | Allocation Classes add the ability to have allocation classes in a pool that are dedicated to serving specific block categories, such as DDT data, metadata, and small file blocks. A pool can opt-in to this feature by adding a 'special' or 'dedup' top-level VDEV.

* OpenZFS 640 - number_to_scaled_string is duplicated in several commandsJason King2017-10-301-21/+97
| | | | | | | | | | | | | | | | | | | Porting Notes: - The OpenZFS patch added nicenum_scale() and nicenum() to a library not used by ZFS. Rather than pull in a new dependency the version of nicenum in lib/libzpool/util.c was simply replaced with the new one.

| | | | | | | | | Fix a regression accidentally introduced by OpenZFS 7280 in ed828c0: since whether to accept NULL as a valid first parameter in strchr() is implementation specific we add an additional check to avoid crashing.
