sema replacement

FreeBSD's new ATA code makes use of kernel counting semaphores (sema(9)) in the queuing code which don't seem to exist in DragonFly*. I think the serializing tokens are the replacement and wanted to see if a) that was the right approach and if so, b) do you use lockmgr or is it preferable to use the tokens directly. TIA

* though, there does seem to be a private implementation in ffs_softdep.c
