perf bench: Fix NULL pointer dereference in "perf bench all"
The for_each_bench() macro must check that the "benchmarks" field of a collection is not NULL before dereferencing it because the "all" collection in particular has a NULL "benchmarks" field (signifying that it has no benchmarks to iterate over). This fixes this NULL pointer dereference when running "perf bench all": [root@ssdandy ~]# perf bench all <SNIP> # Running mem/memset benchmark... # Copying 1MB Bytes ... 2.453675 GB/Sec 12.056327 GB/Sec (with prefault) Segmentation fault (core dumped) [root@ssdandy ~]# Signed-off-by: Patrick Palka <patrick@parcs.ath.cx> Cc: Ingo Molnar <mingo@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1394664051-6037-1-git-send-email-patrick@parcs.ath.cx Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
