perf: Fix up MMAP2 buffer space reservation (2013-09-10 10:42:20 -0300)
----------------------------------------------------------------
perf/urgent fixes:
. Handle perf.data files with no tracepoints in 'perf trace', fixing a
segfault.
. Fix up MMAP2 buffer space reservation, a problem that was caught via
'perf test' consistency tests.
. Add attr->mmap2 support in the tools, a patch that should've been merged
together with the kernel counterpart:
13d7a24 "perf: Add attr->mmap2 attribute to an event".
Merging it allowed us to catch the MMAP buffer space reservation problem via
'perf test'. From Stephane Eranian.
. Make sure we can find PERF_SAMPLE_ID in the variable part of PERF_RECORD_
ring buffer records in 'perf kvm', where direct manipulation of sample_type
was being done.
Fixed by making use of the perf_evlist__set_sample_bit() helper and by
setting the evlist->id_pos in perf_evlist__open(), from Adrian Hunter.
