Hi Josef,
This patch is causing fragmentation with O_DIRECT on preallocated extents
located
-after- the first write to the preallocated extent. This happens regardless of
nodatacow/autodefrag mount options.
Thank you,
Wade

I need everybody to go over this with a fine toothed comb since it is a pretty
big change. I think it is right and it seems to come out right, but if it's not
it will mean we screw up O_DIRECT on snapshotted files with preallocated
extents, so please, make sure it is correct :).
