[for-next-3.11][PATCH 0/5] tracing: Final fixes for the race between open event file and deleting event

From: Steven Rostedt
Date: Thu Aug 01 2013 - 22:56:18 EST


Is all the races that we are aware of between accessing event files and
deleting events covered by these patches? I think I have them all.
Was there any patches that I missed, as there were a lot of threads
and lots of patches sent out, but not all were considered final.

I think I got the main ones that we decided on, but I'm not 100% sure as
my INBOX is overrun by too many activities. It may be a few months before
I go through them all.

I haven't pushed this to my for-next branch as I'm waiting for some feedback
from others in my queue. But I did push it to my ftrace/urgent branch
if you want to look at what will be going there. That branch may rebase
but I wanted to get these patches tested by Fengguang before sending
them to next. And I try not to rebase my for-next branch.
