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 <damien.lemoal@wdc.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
