This patch fixes DM zone resource limits stacking (max open zones and max active zones limits). Patch 1 is new and is added to help catch problems and eventual regressions of the handling of these limits. Changes from v4: - Fixed a typo in a comment in patch 1 - Added patch 2 and changed patch 3 accordingly - Added review tags Changes from v3: - Modify patch 1 to always check the zone resource limits values in disk_update_zone_resources(), including for DM devices that do not use zone write plugging. Simplify patch 2 accordingly by removing the same check and adjustment of the zone resource limits. - Added patch 3 Changes from v2: - Modify patch 1 to return an error for the case where the max open zones limit is greater than the max active zones limit. - Modify patch 2 to avoid duplicated actions on the limits and to remove warnings for unusual zone limits. Changes from v1: - Added patch 1 - Modified patch 2 to not cap the limits for a target with the number of sequential zones mapped but rather to use the device limits as is when more zones than the limits are mapped and 0 otherwise (no limits). Damien Le Moal (4): block: Improve checks on zone resource limits dm: Call dm_revalidate_zones() after setting the queue limits dm: Improve zone resource limits handling dm: Remove unused macro DM_ZONE_INVALID_WP_OFST block/blk-settings.c | 8 ++ block/blk-zoned.c | 20 +++- drivers/md/dm-table.c | 15 ++- drivers/md/dm-zone.c | 220 ++++++++++++++++++++++++++++++++---------- drivers/md/dm.h | 1 + 5 files changed, 207 insertions(+), 57 deletions(-)
