I tried to appy your patches in the following order.
1. [PATCH] exfat: optimize dir-cache
2. [PATCH 1/4] exfat: redefine PBR as boot_sector
3. [PATCH 2/4] exfat: separate the boot sector analysis
4. [PATCH 3/4] exfat: add boot region verification
5. [PATCH 4/4] exfat: standardize checksum calculation

Thanks!
