1 If variable is of Type, use printk format specifier:
2 ---------------------------------------------------------
6 unsigned long %lu or %lx
8 unsigned long long %llu or %llx
12 Raw pointer value SHOULD be printed with %p.
14 u64 SHOULD be printed with %llu/%llx, (unsigned long long):
16 printk("%llu", (unsigned long long)u64_var);
18 s64 SHOULD be printed with %lld/%llx, (long long):
20 printk("%lld", (long long)s64_var);
22 If <type> is dependent on a config option for its size (e.g., sector_t,
23 blkcnt_t, phys_addr_t, resource_size_t) or is architecture-dependent
24 for its size (e.g., tcflag_t), use a format specifier of its largest
25 possible type and explicitly cast to it. Example:
27 printk("test: sector number/total blocks: %llu/%llu\n",
28 (unsigned long long)sector, (unsigned long long)blockcount);
30 Reminder: sizeof() result is of type size_t.
