Hello all, When I change add_clat_sample() in stat.c to call add_log_sample() seven times instead of once, and I set DEF_LOG_ENTRIES=4096, I get the following in the clat log file (note first column is line number in the file): 4089 143, 9832, 0, 131072 4090 143, 9832, 0, 131072 4091 143, 9832, 0, 131072 4092 143, 9832, 0, 131072 4093 143, 9832, 0, 131072 4094 143, 9832, 0, 131072 4095 143, 9832, 0, 131072 4096 143, 9834, 0, 131072 4097 170, 15982, 0, 131072 4098 170, 15982, 0, 131072 4099 170, 15982, 0, 131072 4100 170, 15982, 0, 131072 4101 170, 15982, 0, 131072 4102 170, 15982, 0, 131072 4103 170, 15982, 0, 131072 4104 170, 15985, 0, 131072 4105 170, 15985, 0, 131072 Notice the lonely '9834' value in the center, which should have 7 exact copies of itself but gets cut off right at the buffer size of 4096 entries. So if I'm interpreting this correctly, samples get silently dropped (or not properly printed?) when the buffer fills up. Is this a bug? Am I misinterpreting what the doubly linked list is for? I was under the impression that a new sample buffer should be added to the linked list when the current one fills up.
