AFAICS that's the wrong sha. That commit appears in linux-next, but the commit that actually went into mainline is: b8a94bfb3395 ("kallsyms: increase maximum kernel symbol length to 512") So I'll update the change log to refer to that. cheers > Co-developed-by: Onkarnath <onkarnat...@samsung.com> > Signed-off-by: Onkarnath <onkarnat...@samsung.com> > Signed-off-by: Maninder Singh <maninder...@samsung.com> > --- > arch/powerpc/xmon/xmon.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/arch/powerpc/xmon/xmon.c b/arch/powerpc/xmon/xmon.c > index 728d3c257e4a..70c4c59a1a8f 100644 > --- a/arch/powerpc/xmon/xmon.c > +++ b/arch/powerpc/xmon/xmon.c > @@ -88,7 +88,7 @@ static unsigned long ndump = 64; > static unsigned long nidump = 16; > static unsigned long ncsum = 4096; > static int termch; > -static char tmpstr[128]; > +static char tmpstr[KSYM_NAME_LEN]; > static int tracing_enabled; > > static long bus_error_jmp[JMP_BUF_LEN]; > -- > 2.17.1
