From 545f860883cf02fc152696186436ffe6adf8f1a7 Mon Sep 17 00:00:00 2001 From: Alan Somers Date: Tue, 1 Dec 2020 15:15:18 +0000 Subject: [PATCH] Fix error merging r354116 from OpenZFS When we merged 4c0883fb4af0d5565459099b98fcf90ecbfa1ca1 from OpenZFS (svn r354116), there were some merge conflicts. One of those was resolved incorrectly, causing "zfs receive" to fail to delete snapshots that a "zfs send -R" stream has deleted. This change corrects that merge conflict, and also reduces some harmless diffs vis-a-vis OpenZFS that were also introduced by the same revision. Direct commit to stable/12 because head has moved on to OpenZFS.
