Alexander Motin 8d8e484d9c Remove duplicate dbufs accounting. ... Since AVL already has embedded element counter, use dn_dbufs_count only for dbufs not counted there (bonus buffers) and just add them. This removes two atomics per dbuf life cycle. According to profiler it reduces time spent by dbuf_destroy() inside bottlenecked dbuf_evict_thread() from 13.36% to 9.20% of the core. This counter is used only on illumos, so for FreeBSD it was just a waste of time. MFC after: 2 weeks		2020-02-07 15:50:47 +00:00
