perf test vfs_getname: Disable ~/.perfconfig to get default output
[ Upstream commit 4fe94ce1c6ba678b5f12b94bb9996eea4fc99e85 ]
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
