The shell tests should not redirect useful output to /dev/null, as that
is done automatically by 'perf test' in non verbose mode, so remove that
from the zstd comp/decomp test, fixing up verbose mode.
Before:
$ perf test zstd
68: Zstd perf.data compression/decompression : Ok
$ perf test -v zstd
68: Zstd perf.data compression/decompression :
--- start ---
test child forked, pid 11956
-z, --compression-level[=<n>]
Collecting compressed record file:
Checking compressed events stats:
test child finished with 0
---- end ----
Zstd perf.data compression/decompression: Ok
$
Now:
$ perf test zstd
68: Zstd perf.data compression/decompression : Ok
$ perf test -v zstd
68: Zstd perf.data compression/decompression :
--- start ---
test child forked, pid 12695
Collecting compressed record file:
0+500 records in
72+1 records out
37361 bytes (37 kB, 36 KiB) copied, 9.83796 s, 3.8 kB/s
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.001 MB /tmp/perf.data.rzq, compressed (original 0.004 MB, ratio is 3.679) ]
Checking compressed events stats:
# compressed : Zstd, level = 1, ratio = 4

---- end ----
Zstd perf.data compression/decompression: Ok
