[ Upstream commit 71537e35c324ea6fbd68377a4f26bb93a831ae35 ]
When running delayed inode updates, we do not record the inode's root in the transaction, but we do allocate PREALLOC and thus converted PERTRANS space for it. To be sure we free that PERTRANS meta rsv, we must ensure that we record the root in the transaction.
