lead to race conditions between deleting an event and accessing an event debugfs file. This included a fix to the debugfs system (acked by Greg Kroah-Hartman). We think that all the holes have been patched and hopefully we don't find more. I haven't marked all of them for stable because I need to examine them more to figure out how far back some of the changes need to go. Along the way, some other fixes have been made. Alexander Z Lam fixed some logic where the wrong buffer was being modifed. Andrew Vagin found a possible corruption for machines that actually allocate cpumask, as a reference to one was being zeroed out by mistake. Dhaval Giani found a bad prototype when tracing is not configured. And I not only had some changes to help Oleg, but also finally fixed a long standing bug that Dave Jones and others have been hitting, where a module unload and reload can cause the function tracing accounting to get screwed up. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQEcBAABAgAGBQJR/7FvAAoJEOdOSU1xswtMCAgH/RpxS5mQcQnhrGfu1qnSk+3v CyL1X9IkvgP5f+N59tbU3ZuE8Q3YQvTII35na38fgbHbwWrhYjLSvlf3Pwtre8zr Rjm9b8zA6iSobHu3DyuuupzMsLE+SpBakVSmG6mi8izZyuCi0YHMZMnHTGNnW9Vv YFqkfGgQQWMqiUHLcueetOqWAjR2JiJaLfr47rsRLNflF6dB2MbG/7YbYJ0TBk7E hemVmR7JH7606eJZ6nR7bh/hYv0sL2SSqVVaOHO5nWFLFbI8CybpNVGcoD+nihZY M7LrZT1C1mn3nKrfDhyXy4dwwx6wBON0fY23eJTHMVNnc0tvY1xqH52vTdPILWg= =UfsE -----END PGP SIGNATURE----- Merge tag 'trace-fixes-3.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "Oleg Nesterov has been working hard in closing all the holes that can lead to race conditions between deleting an event and accessing an event debugfs file.
