Rename it to 'delta' - to make them stand apart more clearly. kernel/time/ntp.o: text data bss dec hex filename 2545 114 144 2803 af3 ntp.o.before 2545 114 144 2803 af3 ntp.o.after md5: 1bf0b3be564512279ba7cee299d1d2be ntp.o.before.asm 1bf0b3be564512279ba7cee299d1d2be ntp.o.after.asm Signed-off-by: Ingo Molnar --- diff --git a/kernel/time/ntp.c b/kernel/time/ntp.c index a3fe7ef2d83b..c74eb7d9d854 100644 --- a/kernel/time/ntp.c +++ b/kernel/time/ntp.c @@ -236,7 +236,7 @@ static enum hrtimer_restart ntp_leap_second(struct hrtimer *timer) */ void second_overflow(void) { - s64 time_adj; + s64 delta; /* Bump the maxerror field */ time_maxerror += MAXFREQ / NSEC_PER_USEC; @@ -249,10 +249,11 @@ void second_overflow(void) * Compute the phase adjustment for the next second.
