fsf2_lock_all() calls down_write_nest_lock() to acquire a rw_sem and check
a mutex, but down_write_nest_lock() is designed for two rw_sem accoring to the

mm/mmap.c with two rwsem.
So, it looks it is used wrongly by f2fs.

From: Andi Kleen
Enable metrics printing in --per-core / --per-socket mode. We need
to save the shadow metrics in a unique place. Always use the first
CPU in the aggregation. Then use the same CPU to retrieve the
shadow value later.
Example output:
% perf stat --per-core -a ./BC1s
Performance
From: Andi Kleen
Add a new mode to only print metrics. Sometimes we don't care about
the raw values, just want the computed metrics. This allows more
compact printing, so with -I each sample is only a single line.
This also allows easier plotting and processing with other tools.
The main target
From: Andi Kleen
With all the recently added fields in the perf stat CSV output
we should finally document them in the man page. Do this here.
v2: Fix fields in documentation (Jiri)
v3: fix order of fields again (Jiri)
v4: Change order again.

Only put the frontend/backend stalled cycles into the default
perf stat events when the CPU actually supports them.
This avoids empty columns with --metric-only on newer Intel CPUs.
