[dm-devel] Does dm-thin support GC (garbage collection) ?

[Busby <chaimvy gmail com>]

Hi All,
         The dm-thin supports 'discard' now?Can I think this function
likes SSD's 'TRIM'? If it just discard the block mapped but not
remap(reallocate), the Pool's space will soon be used up . I want to
know whether it supports block reuse ( can use ext4 with '--discard'
test this? ) now or in the future.
        Thanks.


Best regards,
Busby
