Subject[GIT PULL 00/10] perf/core improvements and fixes
Date
Hi Ingo,

Please consider pulling, there is some more stuff in queue to be
processed, but better send in smaller batches,

- Arnaldo

The following changes since commit b3890e4704594fa23abe1395d1fafc97d3214be8:

Merge branch 'perf/hw_breakpoints' into perf/core (2015-01-28 15:48:59 +0100)

are available in the git repository at:

perf symbols: Convert lseek + read to pread (2015-01-29 17:02:01 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Show precise number of samples in at the end of a 'record' session, if
processing build ids, since we will then traverse the whole perf.data file
and see all the PERF_RECORD_SAMPLE records, otherwise stop showing the
previous off-base heuristicly counted number of "samples" (Namhyung Kim).

- Support to read compressed module from build-id cache (Namhyung Kim)

Infrastructure:

- Cache eh/debug frame offset for dwarf unwind (Namhyung Kim)

- Set header version correctly in all cases (Namhyung Kim)

- Set attr.task bit for a tracking event, to be consistent (Namhyung Kim)
perf tools: Use perf_data_file__fd() consistently
perf symbols: Convert lseek + read to pread

- Don't rely on malloc working for sz 0, fixing another problem when
using uClibc (Vineet Gupta)

- Provide stub for missing pthread_attr_setaffinity_np for libcs where this
is not available, such as uClibc (Vineet Gupta)
