In the dir3 data block readahead function, use the regular read verifier to check the block's CRC and spot-check the block contents instead of calling the spot-checking routine directly. This prevents corrupted directory data blocks from being read into the kernel, which can lead to garbage ls output and directory loops (if say one of the entries contains invalid characters).
