Masami Hiramatsu (Google) 0806cb1e6c fprobe: Pass entry_data to handlers
[ Upstream commit 76d0de5729 ]

Pass the private entry_data to the entry and exit handlers so that
they can share the context data, something like saved function
arguments etc.
User must specify the private entry_data size by @entry_data_size
field before registering the fprobe.
