perf probe: Support argument name
Set given names to event arguments. The syntax is same as kprobe-tracer, you can add 'NAME=' right before each argument. e.g. ./perf probe vfs_read foo=file then, 'foo' is set to the argument name as below. ./perf probe -l probe:vfs_read (on vfs_read@linux-2.6-tip/fs/read_write.c with foo) Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <20100412171653.3790.74624.stgit@localhost6.localdomain6> Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
