First perf shell test:
# perf test vfs_getname
60: Add vfs_getname probe to get syscall args filenames: Ok
#
In verbose mode:
# perf test -v vfs_getname
60: Add vfs_getname probe to get syscall args filenames:
--- start ---
test child forked, pid 19146
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
test child finished with 0
---- end ----
Add vfs_getname probe to get syscall args filenames: Ok
#
And if the vmlinux file is not found:
# mv ../build/v4.12.0-rc6+/vmlinux ../build/v4.12.0-rc6+/vmlinux.hidden
# perf test vfs_getname
60: Add vfs_getname probe to get syscall args filenames: Skip
