[CRIU] [PATCH 3/3] dump: Escape double dumping of mangled vDSO

[Cyrill Gorcunov]

When we dump restored program, if there two vdso present (one -- patched
old vdso and a new one where calls are redirected to) -- we need to skip
dumping second vdso. For what we examinate vdso memory with parasite help
and if special mark present -- we remove such vma from the list.
