Subject: [PATCH v3 0/2] perf: measure page fault duration in perf trace
Hi,
Here is another attempt to make the perf-trace subcommand print the
page fault durations.
This solution is based on static tracepoints and it was necessary to
add 2 more tracepoints. I understood that adding tracepoints is a
questionable solution; I can try something else if someone has another
idea.
Alexis.
