md/md-bitmap: remove the last parameter for bimtap_ops->endwrite()

2025-02-08T08:58:11+00:00

commit 4f0e7d0e03b7b80af84759a9e7cfb0f81ac4adae upstream. For the case that IO failed for one rdev, the bit will be mark as NEEDED in following cases: 1) If badblocks is set and rdev is not faulty; 2) If rdev is faulty; Case 1) is useless because synchronize data to badblocks make no sense. Case 2) can be replaced with mddev->degraded. Also remove R1BIO_Degraded, R10BIO_Degraded and STRIPE_DEGRADED since case 2) no longer use them.

md/md-bitmap: factor behind write counters out from bitmap_{start/end}write()

2025-02-08T08:58:11+00:00

commit 08c50142a128dcb2d7060aa3b4c5db8837f7a46a upstream. behind_write is only used in raid1, prepare to refactor bitmap_{start/end}write(), there are no functional changes.

md/md-bitmap: make in memory structure internal

2024-08-27T19:43:16+00:00

Now that struct bitmap_page and bitmap is not used externally anymore, move them from md-bitmap.h to md-bitmap.c (expect that dm-raid is still using define marco 'COUNTER_MAX'). Also fix some checkpatch warnings. Signed-off-by: Yu Kuai Link: https://lore.kernel.org/r/20240826074452.1490072-43-yukuai1@huaweicloud.com Signed-off-by: Song Liu
