94 | * Logging inodes is really tricksy. They are logged in memory format, | |
95 | * which means that what we write into the log doesn't directly translate into | |
96 | * the amount of space they use on disk. | |
97 | * | |
98 | * Case in point - btree format forks in memory format use more space than the | |
99 | * on-disk format. In memory, the buffer contains a normal btree block header so | |
100 | * the btree code can treat it as though it is just another generic buffer. | |
101 | * However, when we write it to the inode fork, we don't write all of this | |
102 | * header as it isn't needed. e.g. the root is only ever in the inode, so | |
103 | * there's no need for sibling pointers which would waste 16 bytes of space. | |
104 | * | |
105 | * Hence when we have an inode with a maximally sized btree format fork, then | |
106 | * amount of information we actually log is greater than the size of the inode | |
107 | * on disk. Hence we need an inode reservation function that calculates all this | |
108 | * correctly. So, we log: | |
109 | * | |
fe4c224a DC |
110 | * - 4 log op headers for object |
111 | * - for the ilf, the inode core and 2 forks | |
23956703 | 112 | * - inode log format object |
fe4c224a DC |
113 | * - the inode core |
114 | * - two inode forks containing bmap btree root blocks. | |
115 | * - the btree data contained by both forks will fit into the inode size, | |
116 | * hence when combined with the inode core above, we have a total of the | |
117 | * actual inode size. | |
118 | * - the BMBT headers need to be accounted separately, as they are | |
119 | * additional to the records and pointers that fit inside the inode | |
120 | * forks. | |
