Re: btrfs-dedupe broken and unsupported but in official wiki

[waxhead <waxhead@dirtcellar.net>]

I have pointed this out before , but I would like to use the opportunity 
again. I, as just a regular user of btrfs would feel more comfortable if 
the dedupe tool was part of btrfs such as for example btrfs filesystem 
dedupe -r /somewhere

Regular users that are somewhat technically able may not know that the 
dedupe fuctions are kernel api's that should not destroy anything even 
if the calling program went berserk.

While this may be obvious to btrfs developers, it is not to regular 
users that may be concerned that a particular tool may wreck havoc on 
their filesystem.
