From 676cac231c069842bf50a04b5c1ebb4bbdf57d53 Mon Sep 17 00:00:00 2001 From: mav Date: Tue, 8 Sep 2009 05:46:38 +0000 Subject: Do not check proper request alignment here in geom_dev in production. It will be checked any way later by g_io_check() in g_io_schedule_down(). It is only needed here to not trigger panic from additional check, when INVARIANTS enabled. So cover it with #ifdef INVARIANTS. It saves two 64bit divisions per request. --- sys/geom/geom_dev.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sys/geom/geom_dev.c') diff --git a/sys/geom/geom_dev.c b/sys/geom/geom_dev.c index b40dea0..8b560ab 100644 --- a/sys/geom/geom_dev.c +++ b/sys/geom/geom_dev.c @@ -371,14 +371,14 @@ g_dev_strategy(struct bio *bp) cp = dev->si_drv2; KASSERT(cp->acr || cp->acw, ("Consumer with zero access count in g_dev_strategy")); - +#ifdef INVARIANTS if ((bp->bio_offset % cp->provider->sectorsize) != 0 || (bp->bio_bcount % cp->provider->sectorsize) != 0) { bp->bio_resid = bp->bio_bcount; biofinish(bp, NULL, EINVAL); return; } - +#endif for (;;) { /* * XXX: This is not an ideal solution, but I belive it to -- cgit v1.1
