XFS dynamic inode allocation has a fundamental limitation in that an inode chunk requires a contiguous extent of a minimum size. Depending on the level of free space fragmentation, inode allocation can fail with ENOSPC where the filesystem might not be near 100% usage. The sparse inodes feature was implemented to provide an inode allocation strategy that maximizes the ability to allocate inodes under free space fragmentation. This test fragments free space and verifies that filesystems that support sparse inode allocation can allocate a minimum percentage of inodes on the fs.
