Btrfs: convert to the new truncate sequence
->truncate() is going away, instead all of the work needs to be done in ->setattr(). So this converts us over to do this. It's fairly straightforward, just get rid of our .truncate inode operation and call btrfs_truncate() directly from btrfs_setsize. This works out better for us since truncate can technically return ENOSPC, and before we had no way of letting anybody know. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
