https://svnweb.freebsd.org/base?view...evision=332523 ... but the arcbuf_addref() function served a second undocumented purpose of updating the ARC access information when taking a hold on a dbuf. Without this logic in place a cached dbuf would not migrate its associated arcbuf_hdrt to the MFU list. This would negatively impact the ARC hit rate, particularly on systems with a small ARC.
