Deadline/NOOP-like I/O schedulers for hardware RAID

[Artem]

Will a Linux Deadline/NOOP-like I/O scheduler implementation using gsched(8) in FreeBSD have any performance improvements on hardware RAID controllers, SSD drives or virtualization like Linux has?

Or there is a FreeBSD way to pass the I/O requests queue management to underlying (RAID/SSD controller or host OS) level?

NOOP scheduler implementation in Linux looks quite simple.

This type of questions is probably better suited for developers, the hackers@ list comes on mind as first.
