The same dmesg result as I, so I didn't see any problem here.

To make it clear, what kernel config and commit are you using when the
test fails?

In my test, if I use the david/for-4.15 branch, it will fails to umount
the fs, due to the known bug if you enabled
CONFIG_BTRFS_FS_CHECK_INTEGRITY (you reported it first).
And for any upstream kernel version like v4.14-rc7 or v4.14, not problem
at all.

BTW, the btrfs-progs version should not affect, since all the problem is
about kernel failing to mount.

Despite that (either disable that option or apply the patch I submitted)
I can't reproduce the bug you reported (which fails to mount the fs).

Thanks,
Qu
