perf probe: Use the last field name as the argument name
Set the last field name to the argument name when the argument is refering a data-structure member. e.g. ./perf probe --add 'vfs_read file->f_mode' Add new event: probe:vfs_read (on vfs_read with f_mode=file->f_mode) This probe records file->f_mode, but the argument name becomes "f_mode". This enables perf-trace command to parse trace event format correctly.
