-From: Sam James <sam@gentoo.org>
-Date: Fri, 24 Nov 2023 21:38:06 +0000
-Subject: [PATCH] Disable zfs_dmu_offset_next_sync tunable by default
-
-As a mitigation until more is understood and fixes are tested & reviewed, change
-the default of zfs_dmu_offset_next_sync from 1 to 0, as it was before
-05b3eb6d232009db247882a39d518e7282630753.
-
-There are no reported cases of The Bug being hit with zfs_dmu_offset_next_sync=1:
-that does not mean this is a cure or a real fix, but it _appears_ to be at least
-effective in reducing the chances of it happening. By itself, it's a safe change
-anyway, so it feels worth us doing while we wait.
