I know Jiri is working on cleanups of the output file, but had this
sitting around for a couple of weeks now. Might as well push it out
for the next baseline. The cleanups of perf-record can be taken
independently.
Ingo: I took a look at leveraging the copy_user_nocache and was not able
to get it to work. I won't have time to come back to it for a while.
Given that the mmap output already improves perf-trace a lot I would
like to get the option into 3.13 and come back to the optimization
later.
David Ahern (4):
perf record: Refactor feature handling into a separate function
perf record: Remove advance_output function
perf record: Remove post_processing_offset variable
perf record: mmap output file - v3
