Bruce Evans e6410301f0 Support filesystems with the not-so-new "sparse_superblocks" feature. ... When this feature is enabled, mke2fs doesn't necessarily allocate a super block and its associated descriptor blocks for every group. The (non-)allocations are reflected in the block bitmap. Since the filesystem code doesn't write to these blocks except for the first superblock, all it has to do to support them is to not count them in ext2_statfs() and not attempt to check them at mount time in ext2_check_blocks_bitmap() (the check has never been enabled in FreeBSD anyway).		2000-11-03 16:41:48 +00:00
