[PATCH -next 13/29] md/raid5: use new apis to suspend array for raid5_store_stripe_size()

From: Yu Kuai
Date: Thu Aug 03 2023 - 09:34:44 EST


From: Yu Kuai <yukuai3@xxxxxxxxxx>

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

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