Subject: [PATCH v8 07/17] fs: Refactoring in alloc_super()
Date: Tue, 03 Jul 2018 18:09:47 +0300 [thread overview]
Message-ID: <153063058712.1818.3382490999719078571.stgit@localhost.localdomain> (raw)
In-Reply-To: <153063036670.1818.16010062622751502.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.
