On older kernels that don't support O_TMPFILE, O_TMPFILE +
[O_RDWR or O_WRONLY] will produce the error ENOENT if
the directory specified in 'pathname' does not exist.

The following patch adds descriptions of the new perf_event_open.2
PERF_SAMPLE_TRANSACTION sample type as added in Linux 3.13.
The descriptions are based on information provided by Andi Kleen,
both in the e-mail
[PATCH 1/6] perf, core: Add generic transaction flags v5
sent to the linux-kernel list as well as an e-mail
[PATCH] Document transaction flags in perf_event_open manpage
sent to the linux-man list.
The implementation is based heavily on the Intel Haswell
processor. Documentation can be found at this page:
http://software.intel.com/en-us/blogs/2013/05/03/intelr-transactional-synchronization-extensions-intelr-tsx-profiling-with-linux-0
as well as in section 18.11.5.1 of volume 3 of the
Intel 64 and IA-32 Architecture Software Developer's Manual.
Also, someone with better manpage formatting skills than I have
should probably investigate why I can't get the last line of
the change to properly tab-align with the .I transaction
heading.
