perf probe: Improve detection of file/function name in the probe pattern
Currently, perf probe considers patterns including a '.' to be a file. However, this causes problems on powerpc ABIv1 where all functions have a leading '.': $ perf probe -F | grep schedule_timeout_interruptible .schedule_timeout_interruptible $ perf probe .schedule_timeout_interruptible Semantic error :File always requires line number or lazy pattern. Error: Command Parse Error. Fix this: - by checking the probe pattern in more detail, and - skipping leading dot if one exists when creating/deleting events. Signed-off-by:Naveen N.
