Adding tracepoints to inline functions adds tracepoint invocation code for each instance where the function is inlined. The resulting increase in kernel code size can have negative impact: - More cache misses in instruction cache - Reduced amount of DMA-capable memory Therefore change all functions implementing I/O instructions from inline to normal functions.
