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

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
