Date: Wed, 28 Jan 2015 12:08:33 +0800 From: lizf@...nel.org To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Josh Triplett <josh@...htriplett.org>, Zefan Li <lizefan@...wei.com> Subject: [PATCH 3.4 73/91] init/Kconfig: Hide printk log config if CONFIG_PRINTK=n From: Josh Triplett <josh@...htriplett.org> 3.4.105-rc1 review patch. If anyone has any objections, please let me know. ------------------ commit 361e9dfbaae84b0b246ed18d1ab7c82a1a41b53e upstream. The buffers sized by CONFIG_LOG_BUF_SHIFT and CONFIG_LOG_CPU_MAX_BUF_SHIFT do not exist if CONFIG_PRINTK=n, so don't ask about their size at all.
