I'm attempting to use /proc/lock_stat to gather some information during some benchmarking runs, but what I find happens is as follows:
1. I boot the system - 2.6.26-rc3 kernel + CONFIG_LOCK_STAT=y
2. I can then look at /proc/lock_stat, and it has valid-looking values
3. I wait a while, do some stuff, but when I look at /proc/lock_stat again the values have not changed.
4. If I clear the counters - echo 0 > /proc/lock_stat - the counters never increase, and no information besides the headers are output when I cat /proc/lock_stat.
Is there something that one needs to do to get counter updates?
Thanks, Alan D. Brunelle
