Steven Rostedt (Red Hat) 289a5a25c5 ring-buffer: Give NMIs a chance to lock the reader_lock ... Currently, if an NMI does a dump of a ring buffer, it disables all ring buffers from ever doing any writes again. This is because it wont take the locks for the cpu_buffer and this can cause corruption if it preempted a read, or a read happens on another CPU for the current cpu buffer. This is a bit overkill. First, it should at least try to take the lock, and if it fails then disable it. Also, there's no need to disable all ring buffers, even those that are unrelated to what is being read. Only disable the per cpu ring buffer that is being read if it can not get the lock for it. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>		2015-05-28 16:47:01 -04:00
