[ Upstream commit 4fe94ce1c6 ]
To get the expected output we have to ignore whatever changes the user
has in its ~/.perfconfig file, so set PERF_CONFIG to /dev/null to
achieve that.
Before:
# egrep 'trace|show_' ~/.perfconfig
[trace]
show_zeros = yes
show_duration = no
show_timestamp = no
show_arg_names = no
show_prefix = yes
# echo $PERF_CONFIG
# perf test "trace + vfs_getname"
70: Check open filename arg using perf trace + vfs_getname: FAILED!
# export PERF_CONFIG=/dev/null
# perf test "trace + vfs_getname"
70: Check open filename arg using perf trace + vfs_getname: Ok
#
After:
# egrep 'trace|show_' ~/.perfconfig
[trace]
show_zeros = yes
show_duration = no
show_timestamp = no
show_arg_names = no
show_prefix = yes
# echo $PERF_CONFIG
# perf test "trace + vfs_getname"
70: 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.
