Benno Evers 5e51aa84f4 perf tools: Check for null when copying nsinfo. ... [ Upstream commit 3f4417d693 ] The argument to nsinfo__copy() was assumed to be valid, but some code paths exist that will lead to NULL being passed. In particular, running 'perf script -D' on a perf.data file containing an PERF_RECORD_MMAP event associating the '[vdso]' dso with pid 0 earlier in the event stream will lead to a segfault. Since all calling code is already checking for a non-null return value, just return NULL for this case as well.
