[PATCH -next v3 14/25] md/raid5: use new apis to suspend array for raid5_store_skip_copy()

From: Yu Kuai <hidden>
Date: 2023-09-28 06:22:43
Also in: dm-devel, lkml
Subsystem: software raid (multiple disks) support, the rest · Maintainers: Song Liu, Yu Kuai, Linus Torvalds

From: Yu Kuai <redacted>

Convert to use new apis, the old apis will be removed eventually.

This is not hot path, so performance is not concerned.
