Subject: [PATCH 4/4] kernel: only define task_struct_whitelist conditionally
Date: Mon, 12 Aug 2019 08:55:24 +0200 [thread overview]
Message-ID: <20190812065524.19959-5-hch@lst.de> (raw)
In-Reply-To: <20190812065524.19959-1-hch@lst.de>
If CONFIG_ARCH_TASK_STRUCT_ALLOCATOR is set task_struct_whitelist is
never called, and thus generates a compiler warning.
Signed-off-by: Christoph Hellwig <hch@lst.de>
