If this were applied via git am, the commit would include all the content from "Corrected Signed-off-by:" Perhaps it would be better to send this as a new patch without the leading 7 lines after the email header > diff --git a/arch/x86/kernel/dumpstack.c b/arch/x86/kernel/dumpstack.c [] > @@ -93,26 +93,15 @@ static void printk_stack_address(unsigned long address, > int reliable, > */ > void show_opcodes(u8 *rip, const char *loglvl) > { > - unsigned int code_prologue = OPCODE_BUFSIZE * 2 / 3; > + const unsigned int prologue = OPCODE_BUFSIZE * 2 / 3; And this might be better as a #define to avoid a few more bytes of stack consumption.
