This isn't really Xen time code, but unchanged Linux time code. I don't know which tree you quoted the code from -- 2.6.18 has similar but not identical. Anyway, I suggest try using the jiffy-comparison macros from <linux/jiffies.h>: time_before(), time_after(), etc. These are designed to work even when jiffies wraps. Feel free to send patch(es) for that, if you test that out and it works okay. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
