-/* load_bitmap_info_data - Sets up the reiserfs_bitmap_info structure from disk.
- * @sb - superblock for this filesystem
- * @bi - the bitmap info to be loaded. Requires that bi->bh is valid.
- *
- * This routine counts how many free bits there are, finding the first zero
- * as a side effect. Could also be implemented as a loop of test_bit() calls, or
- * a loop of find_first_zero_bit() calls. This implementation is similar to
- * find_first_zero_bit(), but doesn't return after it finds the first bit.
- * Should only be called on fs mount, but should be fairly efficient anyways.
- *
- * bi->first_zero_hint is considered unset if it == 0, since the bitmap itself
- * will * invariably occupt block 0 represented in the bitmap. The only
- * exception to this is when free_count also == 0, since there will be no
- * free blocks at all.
