This patch was previously already added to 4.1.12 & 4.2.5 and should be
dropped from all queues. 4.3 has it out of the box, so no need to add it
there either.

Not sure how but apparently you managed to apply it twice, so e.g.
fs/btrfs/ioctl.c:4604 from 4.1.15-rc1 now looks like:

...
if (bctl->flags & ~(BTRFS_BALANCE_ARGS_MASK | BTRFS_BALANCE_TYPE_MASK)) {
	ret = -EINVAL;
	goto out_bctl;
}

if (bctl->flags & ~(BTRFS_BALANCE_ARGS_MASK | BTRFS_BALANCE_TYPE_MASK)) {
	ret = -EINVAL;
	goto out_bargs;
}
...

cheers,
