From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Fix printk format warnings (seen on i386 build): ../drivers/block/zram/zram_drv.c:678:4: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘ssize_t’ [-Wformat=] ../drivers/block/zram/zram_drv.c:678:4: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘time64_t’ [-Wformat=] time64_t is 64 bits (and signed), so printing it should use %lld, not %ld. %ld (long) is only 32 bits on several architectures.
