The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly Cc: netdev@vger.kernel.org Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: S.Çağlar Onur <redacted> --- drivers/net/tokenring/3c359.c | 21 +++++++++++---------- 1 files changed, 11 insertions(+), 10 deletions(-)
