If anyone has any objections, please let me know. ------------------ From: Heming Zhao commit f921da2c34692dfec5f72b5ae347b1bea22bb369 upstream. Commit 23aab037106d ("ocfs2: fix UBSAN warning in ocfs2_verify_volume()") introduced a regression bug. The blksz_bits value is already converted to CPU endian in the previous code; therefore, the code shouldn't use le32_to_cpu() anymore.
