David,
When I am doing a profiling of kernel compile with 32 threads on a 4
socket westmere machine, I found that perf record terminated right away
for the version of perf in 3.7 kernel source tree.
There's no profile data recroded and the compile is running in
background.
$ make -j32 &
then
$ sudo /test/perf record -a -g -f sleep 5
sleep: Terminated
This should fix it. I guess not all return codes were meant to be checked.
