perf tools: Handle failure case in trace_report()

2013-03-21T16:30:52Z

If pevent allocation in read_trace_init() fails, trace_report() will return -1 and *ppevent is set to NULL. Its callers should check this case and handle it properly. This is also a preparation for the removal of *die() calls.

perf tools: Get rid of redundant _FILE_OFFSET_BITS definition

perf evlist: Remove cpus and threads arguments from perf_evlist__new()

2013-03-15T16:06:01Z

It's almost always used with NULL for both arguments. Get rid of the arguments from the signature and use perf_evlist__set_maps() if needed.

perf tools: Fix calloc argument ordering

2013-02-06T21:09:28Z

A sweep of the kernel for regex "kcalloc(sizeof" turned up 2 reversed args, fixed in commit d3d09e18203dba16a9dbdb2b4cc673d90748cdd1 ("EDAC: Fix kcalloc argument order") and also fixed in the networking commit a1b1add07fa794974573d93483d68e373edfe7bd ("gro: Fix kcalloc argument order"). I know that was the regex used, because on seeing the 1st of these changes, I wondered "how many other instances of this are there" and I happened to just use "calloc(sizeof" as a regex and it in turn found these additional reversed args instances in the perf code. In the kcalloc cases, the changes are cosmetic, since the numbers are simply multiplied. I had no desire to go data mining in userspace to see if the same thing held true there, however.
