perf test shell: Replace '|&' with '2>&1 |' to work with more shells
Since we do not specify bash (and/or zsh) as a requirement, use the
standard error redirection that is more widely supported.
BEFORE:
$ sudo perf test -v 62
62: Check open filename arg using perf trace + vfs_getname:
--- start ---
test child forked, pid 27305
./tests/shell/trace+probe_vfs_getname.sh: 20: ./tests/shell/trace+probe_vfs_getname.sh: Syntax error: "&" unexpected
test child finished with -2
---- end ----
Check open filename arg using perf trace + vfs_getname: Skip
AFTER:
$ sudo perf test -v 62
64: Check open filename arg using perf trace + vfs_getname :
--- start ---
test child forked, pid 23008
Added new event:
probe:vfs_getname (on getname_flags:72 with pathname=result->name:string)
You can now use it in all perf tools, such as:
perf record -e probe:vfs_getname -aR sleep 1
0.361 ( 0.008 ms): touch/23032 openat(dfd: CWD, filename: /tmp/temporary_file.VEh0n, flags: CREAT|NOCTTY|NONBLOCK|WRONLY, mode: IRUGO|IWUGO) = 4
test child finished with 0
---- end ----
Check open filename arg using perf trace + vfs_getname: Ok
Similar to commit 35435cd06081, with the same title.
