Log:
Make ada(4) driver to control device write cache, same as ata(4) does.
Add kern.cam.ada.write_cache sysctl/tunable to control it alike hw.ata.wc.
how hard would it be to support per device sysctls/tunables? i'd really like to
do:
kern.cam.ada.0.write_cache=0 (root fs)
kern.cam.ada.1.write_cache=1 (/usr, /var, etc.)
Not really hard. I'll do it now.
