Offline Deduplication for Btrfs V2
Just a quick update, I''ve dropped the hashing stuff in favor of doing a memcmp
in the kernel to make sure the data is still the same. The thing that takes a
while is reading the data up from disk, so doing a memcmp of the entire buffer
isn''t that big of a deal, not to mention there''s a possiblity for malicious
users if there is a problem with the hashing algorithms we

Offline Deduplication for Btrfs
Here are patches to do offline deduplication for Btrfs. It works well for the
cases it''s expected to, I''m looking for feedback on the ioctl interface and

being able to set a different blocksize). If this interface is acceptable I
will flesh out the userspace app a little more, but I believe the
