Subject: [PATCH v7 REBASED 07/17] fs: Refactoring in alloc_super()
Date: Mon, 18 Jun 2018 12:45:58 +0300 [thread overview]
Message-ID: <152931515883.28457.15515405237855359874.stgit@localhost.localdomain> (raw)
In-Reply-To: <152931506756.28457.5620076974981468927.stgit@localhost.localdomain>
Do two list_lru_init_memcg() calls after prealloc_super().
destroy_unused_super() in fail path is OK with this.
Next patch needs such the order.
