[linux-lvm] LVM generates wrong low_water_mark value in thin-pool's table

I found that the <low_water_mark> parameter of thin-pool's table might be
wrong. In kernel, the this parameter is the number of free blocks. However,
LVM commit 99237f0908d87592815f4bdf3c239e8a108e835c sets this value as the
number of USED blocks, according
to activation_thin_pool_autoextend_threshold_CFG. Is that a bug?
