Looks like a deeper bug has been exposed due to the way bclone works? They're finding issues now on ZFS versions predating bclone

Edit: yep, it's an older bug. Set zfs_dmu_offset_next_sync=0 to save your data

Not sure what's your point. The comment I linked to just confirmed that the bug (whichever it might be) has reproduced on FreeBSD.

Nope, somebody managed to reproduce this issue even with zfs_dmu_offset_next_sync=0

Apply this patch, it appears to be the real fix.
