What's the need of array with zero elements?
...u would use it like this:
struct bts_action *var = kmalloc(sizeof(*var) + extra, GFP_KERNEL);
This used to be not standard and was considered a hack (as Aniket said), but it was standardized in C99. The standard format for it now is:
struct bts_action {
u16 type;
u16 size;
u8 data...

Efficient Algorithm for Bit Reversal (from MSB->LSB to LSB->MSB) in C
...eversed bits of v; first get LSB of v
int s = sizeof(v) * CHAR_BIT - 1; // extra shift needed at end
for (v >>= 1; v; v >>= 1)
{
r <<= 1;
r |= v & 1;
s--;
}
r <<= s; // shift when v's highest bits are zero
