BTW, David seems to update his branch more often in his git.kernel.org
branch than github.

So it's possible that the branch from github is out dated.

For v4.14-rc7, even I enabled all the btrfs related configs, I still
can't reproduce it.
------
$ zcat /proc/config.gz  | grep BTRFS
CONFIG_BTRFS_FS=m
CONFIG_BTRFS_FS_POSIX_ACL=y
CONFIG_BTRFS_FS_CHECK_INTEGRITY=y
CONFIG_BTRFS_FS_RUN_SANITY_TESTS=y
CONFIG_BTRFS_DEBUG=y
CONFIG_BTRFS_ASSERT=y
------

So there is something strange happened.

Thanks,
