Arnd Bergmann e93d12ae3b null_blk: use sector_div instead of do_div ... Dividing a sector_t number should be done using sector_div rather than do_div to optimize the 32-bit sector_t case, and with the latest do_div optimizations, we now get a compile-time warning for this: arch/arm/include/asm/div64.h:32:95: note: expected 'uint64_t * {aka long long unsigned int *}' but argument is of type 'sector_t * {aka long unsigned int *}' drivers/block/null_blk.c:521:81: warning: comparison of distinct pointer types lacks a cast This changes the newly added code to use sector_div. It is a simplified version of the original patch, as Linus Torvalds pointed out that we should not be using an expensive division function in the first place. This version was suggested by Matias Bjorling.
