commit 7ca4be45a0255ac8f08c05491c6add2dd87dd4f8 limited csum items to PAGE_CACHE_SIZE. It used min() with incompatible types in 32bit which generates warnings: fs/btrfs/file-item.c: In function ‘btrfs_csum_file_blocks’: fs/btrfs/file-item.c:717: warning: comparison of distinct pointer types lacks a cast This uses min_t(u32,) to fix the warnings. u32 seemed reasonable because btrfs_root->leafsize is u32 and PAGE_CACHE_SIZE is unsigned long.
