dm-raid: don't set io_min and io_opt for raid1

2025-09-25T09:16:46Z

commit a86556264696b797d94238d99d8284d0d34ed960 upstream. These commands modprobe brd rd_size=1048576 vgcreate vg /dev/ram* lvcreate -m4 -L10 -n lv vg trigger the following warnings: device-mapper: table: 252:10: adding target device (start sect 0 len 24576) caused an alignment inconsistency device-mapper: table: 252:10: adding target device (start sect 0 len 24576) caused an alignment inconsistency The warnings are caused by the fact that io_min is 512 and physical block size is 4096. If there's chunk-less raid, such as raid1, io_min shouldn't be set to zero because it would be raised to 512 and it would trigger the warning. Signed-off-by: Mikulas Patocka Reviewed-by: Martin K.

md: rename recovery_cp to resync_offset

2025-08-28T14:34:45Z

[ Upstream commit 907a99c314a5a695e35acff78ac61f4ec950a6d3 ] 'recovery_cp' was used to represent the progress of sync, but its name contains recovery, which can cause confusion. Replaces 'recovery_cp' with 'resync_offset' for clarity.

md/dm-raid: remove max_write_behind setting limit

2025-05-30T07:47:23Z

The comments said 'vaule in kB', while the value actually means the number of write_behind IOs. And since md-bitmap will automatically adjust the value to max COUNTER_MAX / 2, there is no need to fail early. Also move some macros that is only used md-bitmap.c.

md: record dm-raid gendisk in mddev

2025-05-10T08:12:19Z

Following patch will use gendisk to check if there are normal IO completed or inflight, to fix a problem in mdraid that foreground IO can be starved by background sync IO in later patches.

And move the condition "if (mddev->bitmap)" into md_bitmap_resize() as well, on the one hand make code cleaner, on the other hand try not to access bitmap directly.
