From d7e640cf95f72deeca501d34afed59a0bc9d7940 Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Wed, 10 Nov 2021 16:14:32 -0800 Subject: [PATCH] Restore dirty dnode detection logic In addition to flushing memory mapped regions when checking holes, commit de198f2d95 modified the dirty dnode detection logic to check the dn->dn_dirty_records instead of the dn->dn_dirty_link. Relying on the dirty record has not be reliable, switch back to the previous method.
