* spare ones. Later, when we come to actually claim the inode in the bitmap
* it may be that it was taken. In that case the allocator will undo this
* reservation and try again.
*
* The inode allocator does not physically alter the superblock. But we still
* set sb->s_dirt, because the superblock was "logically" altered - we need to
* go and add up the free inodes counts again and flush out the superblock.
