Merge tag 'exfat-for-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/exfat

Pull exfat updates from Namjae Jeon:

 - Implement FALLOC_FL_ALLOCATE_RANGE to add support for preallocating
   clusters without zeroing, helping to reduce file fragmentation

 - Add a unified block readahead helper for FAT chain conversion, bitmap
   allocation, and directory entry lookups

 - Optimize exfat_chain_cont_cluster() by caching buffer heads to
   minimize mark_buffer_dirty() and mirroring overhead during
   NO_FAT_CHAIN to FAT_CHAIN conversion

 - Switch to truncate_inode_pages_final() in evict_inode() to prevent
   BUG_ON caused by shadow entries during reclaim

 - Fix a 32-bit truncation bug in directory entry calculations by
   ensuring proper bitwise coercion

 - Fix sb->s_maxbytes calculation to correctly reflect the maximum
   possible volume size for a given cluster size, resolving xfstests
   generic/213

 - Introduced exfat_cluster_walk() helper to traverse FAT chains by a
   specified step, handling both ALLOC_NO_FAT_CHAIN and ALLOC_FAT_CHAIN
   modes

 - Introduced exfat_chain_advance() helper to advance an exfat_chain
   structure, updating both the current cluster and remaining size

 - Remove dead assignments and fix Smatch warnings
