SVN rev 216807 on 2010-12-29 20:35:36Z by alc
There is no point in vm_contig_launder{,_page}() flushing held pages,
instead skip over them. As long as a page is held, it can't be reclaimed by
contigmalloc(M_WAITOK). Moreover, a held page may be undergoing
modification, e.g., vmapbuf(), so even if the hold were released before the
completion of contigmalloc(), the page might have to be flushed again.
