sorry, I didn't know about your patch. Can you please resubmit it with
the following changes?
- Don't use camelCase (findNextPacket)
- Remove disabled printk() calls.
- Only one statement per line.
if (unlikely(lost = pos - start)) {
while (likely((p = findNextPacket(buf, p, count, pktsize)) < count)) {
- Add white space between while and the opening brace.
while(likely(pos < count)) {
- Use unsigned data types for pos and pktsize:
static inline int findNextPacket(const u8 *buf, int pos, size_t count,
const int pktsize)
The CodingStyle[1] document can serve as a guideline on how to properly
format kernel code.
Does the excessive use of likely() and unlikely() really improve the
performance or is it just a guess?
Regards,
Andreas
