[pve-devel] vma extract force flag

[Ben Dailey]

The hope would be to get the benefits of nop-write from the underlying ZFS
filesystem therefore increasing performance and reducing snapshot size
without the need for deduplication being enabled. I have often found large
deletes on ZFS to sometimes not be very performant as well, especially if
deduplication is enabled.

Praise the Lord!
