[linux-lvm] thin discards

[Raymond Jennings]

Gentoo

sys-kernel/gentoo-sources-3.10.1
sys-fs/lvm2-2.02.97-r1

I don't know if the pool device is capable of trim support.  I do know that
the underlying device, a seagate hard drive, does not support discard.
 However one would think that thin volumes have their own discard handling
to deallocate internally, possibly passing a discard down to the underlying
block device as needed.
