[PATCH -next v2 06/28] md: use new apis to suspend array for level_store()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
