- * For an inode to be locked in a transaction, the inode lock, as

- * that the inode can be involved in only 1 transaction at a time.
- * Lock recursion is handled on the io lock, but only for lock modes

- * go from not holding the io lock to having it EXCL or SHARED.

- *
- * If we don't already own the inode, use xfs_iget() to get it.
- * Since the inode log item structure is embedded in the incore
