From 118aa47c7072bce05fc39bd40a1c0a90caed72ab Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Thu, 11 Oct 2018 11:45:30 +0900 Subject: [PATCH] dm linear: fix linear_end_io conditional definition The dm-linear target is independent of the dm-zoned target. For code requiring support for zoned block devices, use CONFIG_BLK_DEV_ZONED instead of CONFIG_DM_ZONED. While at it, similarly to dm linear, also enable the DM_TARGET_ZONED_HM feature in dm-flakey only if CONFIG_BLK_DEV_ZONED is defined. Fixes: beb9caac211c1 ("dm linear: eliminate linear_end_io call if CONFIG_DM_ZONED disabled") Fixes: 0be12c1c7fce7 ("dm linear: add support for zoned block devices") Cc: stable@vger.kernel.org Signed-off-by: Damien Le Moal Signed-off-by: Mike Snitzer --- drivers/md/dm-flakey.c | 2 ++ drivers/md/dm-linear.c | 4 ++-- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/md/dm-flakey.c b/drivers/md/dm-flakey.c index 21d126a5078c..32aabe27b37c 100644 --- a/drivers/md/dm-flakey.c +++ b/drivers/md/dm-flakey.c @@ -467,7 +467,9 @@ static int flakey_iterate_devices(struct dm_target *ti, iterate_devices_callout_ static struct target_type flakey_target = { .name = "flakey", .version = {1, 5, 0}, +#ifdef CONFIG_BLK_DEV_ZONED .features = DM_TARGET_ZONED_HM, +#endif .module = THIS_MODULE, .ctr = flakey_ctr, .dtr = flakey_dtr, diff --git a/drivers/md/dm-linear.c b/drivers/md/dm-linear.c index 172f6fa83c0d..2f7c44a006c4 100644 --- a/drivers/md/dm-linear.c +++ b/drivers/md/dm-linear.c @@ -102,7 +102,7 @@ static int linear_map(struct dm_target *ti, struct bio *bio) return DM_MAPIO_REMAPPED; } -#ifdef CONFIG_DM_ZONED +#ifdef CONFIG_BLK_DEV_ZONED static int linear_end_io(struct dm_target *ti, struct bio *bio, blk_status_t *error) { @@ -210,7 +210,7 @@ static size_t linear_dax_copy_to_iter(struct dm_target *ti, pgoff_t pgoff, static struct target_type linear_target = { .name = "linear", .version = {1, 4, 0}, -#ifdef CONFIG_DM_ZONED +#ifdef CONFIG_BLK_DEV_ZONED .end_io = linear_end_io, .features = DM_TARGET_PASSES_INTEGRITY | DM_TARGET_ZONED_HM, #else
