Baokun Li 6a28b5c990 ext4: support large block size in ext4_calculate_overhead() ... ext4_calculate_overhead() used a single page for its bitmap buffer, which worked fine when PAGE_SIZE >= block size. However, with block size greater than page size (BS > PS) support, the bitmap can exceed a single page. To address this, we now use kvmalloc() to allocate memory of the filesystem block size, to properly support BS > PS.
