By default, this scheduler implements the old behavior. In addition, an advanced adaptive scheduler is available. Along with the scheduler, SATA disks can now use Queued Trims with devices that support them. Details about the new scheduler are available in the I/O Scheduling in FreeBSD's CAM Subsystem article (PDF) or from the BSDCan 2015 talk. I updated my source today, but CAM_ADAPTIVE_IOSCHED yields an error about an unknown option. If I use CAM_NETFLIX_IOSCHED the kernel compiles. Is the name CAM_NETFLIX_IOSCHED changing to CAM_ADAPTIVE_IOSCHED?
That is my understanding, yes. Warner can certainly explain it better than I can, so CCed.
