[PATCH] perf, map: Don't try to find DSOs in SYSV maps

From: Don Zickus
Date: Tue Aug 19 2014 - 22:31:47 EST


We are seeing a lot of the following with regards to SYSV memory

Failed to open /SYSV0000279c, continuing without symbols

We don't believe this memory will have DSO info, so treat it like the heap and
stack for now and skip it to prevent the warning.
