Subject: [PATCH v2 0/6] tracing: open/delete fixes

Hello.

Testing: seems to work, but assumes that debugs was fixed too. Hopefully
"debugfs: debugfs_remove_recursive() must not rely on list_empty(d_subdirs)"
is fine.

(We should probably make debugfs_remove_recursive() to return the error
 and trace_events.c should warn if it fails)

However: I am still testing this patches, so this is still mostly for
review. I'll report if I find anything, but to remind we have other
bugs which need more fixes. And in fact I need to re-read this series
to convince myself it should work, I was distracted by the unexpected
problem in debugfs.

Changes: a lot but all cosmetic, addresses the comments from Steven.

Steven, 1/6 was not changed, I assume you agreed with my reply.

Masami, I'll appreciate your review ;)

Oleg.
