vdso / vvar address overlapping checking in older version of mtcp_restart.c

[ylkuo96]

Hi,

I have a question about checking vvar / vdso address is overlapped or not in older version of mtcp_restart.c

From the source code, before mapping vdso back to old vdso location, and mapping vvar back to old vvar location, we check the following four situations:

1. (new vdso, old vdso)
2. (new vdso, old vvar)
3. (new vvar, old vdso)
4. (new vdso, old vvar)

But actually, the fourth should be (new vvar, old vvar), right ?
Please correct me if I'm wrong.

Thanks !!
