From 5dea271b6d87bd1d79a59c1d5baac2596a841c37 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 23 Jul 2009 20:30:42 +0100 Subject: dm table: pass correct dev area size to device_area_is_valid Incorrect device area lengths are being passed to device_area_is_valid(). The regression appeared in 2.6.31-rc1 through commit 754c5fc7ebb417b23601a6222a6005cc2e7f2913. With the dm-stripe target, the size of the target (ti->len) was used instead of the stripe_width (ti->len/#stripes). An example of a consequent incorrect error message is: device-mapper: table: 254:0: sdb too small for target Signed-off-by: Mike Snitzer Signed-off-by: Alasdair G Kergon --- include/linux/device-mapper.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/linux/device-mapper.h b/include/linux/device-mapper.h index 0d6310657f32..655e7721580a 100644 --- a/include/linux/device-mapper.h +++ b/include/linux/device-mapper.h @@ -84,7 +84,7 @@ typedef int (*dm_merge_fn) (struct dm_target *ti, struct bvec_merge_data *bvm, typedef int (*iterate_devices_callout_fn) (struct dm_target *ti, struct dm_dev *dev, - sector_t physical_start, + sector_t start, sector_t len, void *data); typedef int (*dm_iterate_devices_fn) (struct dm_target *ti, @@ -104,7 +104,7 @@ void dm_error(const char *message); * Combine device limits. */ int dm_set_device_limits(struct dm_target *ti, struct dm_dev *dev, - sector_t start, void *data); + sector_t start, sector_t len, void *data); struct dm_dev { struct block_device *bdev; -- cgit v1.2.3
