Comment 70 for bug 2044657

Just updated my pool today and then remembered hearing about this bug. Guess I should have searched first. Looking forward to the proposed fix getting released. Thanks for the patch. :)

For now, I'm using the suggestion of setting `zfs_dmu_offset_next_sync=0` based on this: https://www.reddit.com/r/zfs/comments/1826lgs/psa_its_not_block_cloning_its_a_data_corruption.

Plopped the kernel param into `/etc/default/grub` and did an `update-grub` to make it persistent until the patch is out.
