Hi Andrew, After merging the akpm-current tree, today's linux-next build (arm multi_v7_defconfig) produced this warning: In file included from fs/fat/inode.c:24:0: fs/fat/inode.c: In function '__fat_get_block': fs/fat/inode.c:163:9: warning: format '%ld' expects argument of type 'long int', but argument 5 has type 'sector_t {aka long long unsigned int}' [-Wformat=] "invalid FAT chain (i_pos %lld, last_block %ld)", ^ fs/fat/fat.h:397:24: note: in definition of macro 'fat_fs_error' __fat_fs_error(sb, 1, fmt , ## args) ^~~ Introduced by commit 3bdac70a1921 ("fat: use fat_fs_error() instead of BUG_ON() in __fat_get_block()") -- Cheers, Stephen Rothwell
