function, implementing the sysctl vfs.ffs.set_bufoutput (not used in the tree yet). - The current directory vnode dereference is unsafe since fd_cdir could be changed and unreferenced, lock the filedesc around and vref the fd_cdir. - The VTOI() conversion of the fd_cdir is unsafe without first checking that the vnode is indeed from an FFS mount, otherwise the code dereferences a random memory. - The cdir could be reclaimed from under us, lock it around the checks. - The type of the fp vnode might be not a disk, or it might have changed while the thread was in flight, check the type.
