| |
When compiling a 32bit kernel with CONFIG_LBDAF=n the compiler complains like shown below. Fix this warning by instead using sector_div() which is provided by the kernel.h header file.
fs/nfs/blocklayout/extents.c: In function ‘normalize’: include/asm-generic/div64.h:43:28: warning: comparison of distinct pointer types lacks a cast [enabled by default] fs/nfs/blocklayout/extents.c:47:13: note: in expansion of macro ‘do_div’ nfs/blocklayout/extents.c:47:2: warning: right shift count >= width of type [enabled by default] fs/nfs/blocklayout/extents.c:47:2: warning: passing argument 1 of ‘__div64_32’ from incompatible pointer type [enabled by default] include/asm-generic/div64.h:35:17: note: expected ‘uint64_t *’ but argument is of type ‘sector_t *’ extern uint32_t __div64_32(uint64_t *dividend, uint32_t divisor);
