[PATCH] ext4 64 bit divide fix

2006-10-11T18:14:18Z

With CONFIG_LBD=n, sector_div() expands to a plain old divide. But ext4 is _not_ passing in a sector_t as the first argument, so... fs/built-in.o: In function `ext4_get_group_no_and_offset': fs/ext4/balloc.c:39: undefined reference to `__umoddi3' fs/ext4/balloc.c:41: undefined reference to `__udivdi3' fs/built-in.o: In function `find_group_orlov': fs/ext4/ialloc.c:278: undefined reference to `__udivdi3' fs/built-in.o: In function `ext4_fill_super': fs/ext4/super.c:1488: undefined reference to `__udivdi3' fs/ext4/super.c:1488: undefined reference to `__umoddi3' fs/ext4/super.c:1594: undefined reference to `__udivdi3' fs/ext4/super.c:1601: undefined reference to `__umoddi3' Fix that up by calling do_div() directly. Also cast the arg to u64. do_div() is only defined on u64, and ext4_fsblk_t is supposed to be opaque. Note especially the changes to find_group_orlov(). It was attempting to do do_div(int, unsigned long long); which is royally screwed up. Switched it to plain old divide. Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
