#       "Vaibhav Nagarnaik found that modifying the ring buffer size could cause
#        a huge latency in the system because it does a while loop to free pages
#        without releasing the CPU (on non preempt kernels). In a case where there
#        are hundreds of thousands of pages to free it could actually cause a system
#        stall. A properly place cond_resched() solves this issue."
