The name of the sysctl really sucks, it just control whether caching is enabled/disabled. Now, having said that I realize there are multiple sysctl that contain "cache" in their names. But can you come up with a more descriptive name, directly relating to what the sysctl does and now what its actual effects are :)? Also, aren't caches enabled by the kernel when the system is booting, according to SDM1/section 9.3 caches are disabled after reset and I assume the kernel does enable them when it's booting?
