Subject[PATCH 0/4] perf tools: Support reading PERF_FORMAT_LOST
Date
Hello,

The kernel v6.0 added PERF_FORMAT_LOST which can read a number of lost
samples for the given event. As it can change the output format of
read(2) and perf sample data, it needs to access them carefully.

You can get the code from 'perf/read-lost-v1' brach on

git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
