Author: mav Date: Wed May 8 01:35:43 2019 New Revision: 347240 URL: https://svnweb.freebsd.org/changeset/base/347240 Log: Fix dataset name comparison in zfs_compare(). The code never returned match comparing two datasets (not snapshots). As result, uu_avl_find(), called from zfs_callback(), never succeeded, allowing to add same dataset into the list multiple times, for example: # zfs get name pers pers pers@z pers@z NAME PROPERTY VALUE SOURCE pers name pers - pers name pers - pers@z name pers@z - With the patch: # zfs get name pers pers pers@z pers@z NAME PROPERTY VALUE SOURCE pers name pers - pers@z name pers@z - MFC after: 1 week Sponsored by: iXsystems, Inc.
