Kirk McKusick e9cc475851 Collect read and write counts for filesystems. This new code ... drops the counting in bwrite and puts it all in spec_strategy. I did some tests and verified that the counts collected for writes in spec_strategy is identical to the counts that we previously collected in bwrite. We now also get read counts (async reads come from requests for read-ahead blocks). Note that you need to compile a new version of mount to get the read counts printed out. The old mount binary is completely compatible, the only reason to install a new mount is to get the read counts printed.
