From: Josh Triplett <josh@xxxxxxxxxxxxxxxx> 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. Signed-off-by: Josh Triplett <josh@xxxxxxxxxxxxxxxx> Acked-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> [lizf: Backported to 3.4: - drop the change to CONFIG_LOG_CPU_MAX_BUF_SHIFT as it doesn't exist in 3.4] Signed-off-by: Zefan Li <lizefan@xxxxxxxxxx> --- init/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/init/Kconfig b/init/Kconfig index 6cfd71d..f1b0e78 100644 --- a/init/Kconfig +++ b/init/Kconfig @@ -560,6 +560,7 @@ config LOG_BUF_SHIFT int "Kernel log buffer size (16 => 64KB, 17 => 128KB)" range 12 21 default 17 + depends on PRINTK help Select kernel log buffer size as a power of 2.
