Theodore Ts'o c9200760da ext4: check for invalid block size early when mounting a file system ... Check for valid block size directly by validating s_log_block_size; we were doing this in two places. First, by calculating blocksize via BLOCK_SIZE << s_log_block_size, and then checking that the blocksize was valid. And then secondly, by checking s_log_block_size directly. The first check is not reliable, and can trigger an UBSAN warning if s_log_block_size on a maliciously corrupted superblock is greater than 22. This is harmless, since the second test will correctly reject the maliciously fuzzed file system, but to make syzbot shut up, and because the two checks are duplicative in any case, delete the blocksize check, and move the s_log_block_size earlier in ext4_fill_super().
