* on disk. Hence we need an inode reservation function that calculates all this
* correctly. So, we log:
*
- * - log op headers for object
+ * - 4 log op headers for object
+ * - for the ilf, the inode core and 2 forks
* - inode log format object
- * - the entire inode contents (core + 2 forks)
- * - two bmap btree block headers
+ * - the inode core
+ * - two inode forks containing bmap btree root blocks.
+ * - the btree data contained by both forks will fit into the inode size,
+ * hence when combined with the inode core above, we have a total of the
+ * actual inode size.
+ * - the BMBT headers need to be accounted separately, as they are
+ * additional to the records and pointers that fit inside the inode
+ * forks.
