btrfs-progs 4.6.1 kernel-4.8.0-0.rc1.git0.1.fc25.x86_64 Details in the bug, which also includes btrfs-debug-tree and btrfs-image. I haven't tried to reproduce, so it could be a one off, and there's no enospc_debug mount option used. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
