From ec9c42ec793d428e99fdd219867b31932034b138 Mon Sep 17 00:00:00 2001 From: Márton Németh Date: Sun, 10 Jan 2010 13:39:52 +0100 Subject: block: make xenbus device id constant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ids field of the struct xenbus_device_id is constant in so it is worth to make blkfront_ids also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // Signed-off-by: Márton Németh Cc: Julia Lawall Cc: cocci@diku.dk Signed-off-by: Jens Axboe --- drivers/block/xen-blkfront.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/block/xen-blkfront.c') diff --git a/drivers/block/xen-blkfront.c b/drivers/block/xen-blkfront.c index 05a31e55d278..a84702d1a35e 100644 --- a/drivers/block/xen-blkfront.c +++ b/drivers/block/xen-blkfront.c @@ -1050,7 +1050,7 @@ static const struct block_device_operations xlvbd_block_fops = }; -static struct xenbus_device_id blkfront_ids[] = { +static const struct xenbus_device_id blkfront_ids[] = { { "vbd" }, { "" } }; -- cgit v1.2.3
