perf probe: Support tracing an entry of array
Add array-entry tracing support to perf probe. This enables to trace an entry of array which is indexed by constant value, e.g. array[0]. For example: $ perf probe -a 'bio_split bi->bi_io_vec[0]' Cc: Paul Mackerras <paulus@samba.org> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <20100519195742.2885.5344.stgit@localhost6.localdomain6> Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
