I was cleaning out my INBOX and found two fixes from zhangwei from a year ago that were lost in my mail. These fix an inconsistency between trace_puts() and the way trace_printk() works. The reason this is important to fix is because when trace_printk() doesn't have any arguments, it turns into a trace_puts(). Not being able to enable a stack trace against trace_printk() because it does not have any arguments is quite confusing. Also, the fix is rather trivial and low risk. While porting some changes to PowerPC I discovered that it still has the function graph tracer filter bug that if you also enable stack tracing the function graph tracer filter is ignored. I fixed that up. Finally, Martin Lau, fixed a bug that would cause readers of the ftrace ring buffer to block forever even though it was suppose to be NONBLOCK. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJTxfAHAAoJEKQekfcNnQGueDkH/jQ/FgNPw+GbKuNpZwWqMQds ivGM8yb6NgmlDQx60oBOL9TduKN2LCqW3HWDoyzduSozuLUxpRTPWtVThKo0Q9Fp FPHWewdrX7DwWkyEqeG7FAAhjqPedgEZoDOwy7BArzJYpHcpex42trDY4BhjPrlM ESA+/M+Xm1vGCJzcNSqNHYE/mF/tHptdM1mlLZ3g9ql49MiTbQxEMbHX7lih24sv AzNP1SlisYN5CkX4hbRGhCYkZdmdVZt/xiyBAQRWCGFx+jsdJbMXDJnevDCdU9Mv GNtKwqsi1/GeE5nvKxZyQKsDEE98Pd8LyQ0kDqKpAfTutqNE4mpWJkCxUqTmE4Q= =aFqO -----END PGP SIGNATURE----- Merge tag 'trace-fixes-v3.16-rc5-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "A few more fixes for ftrace infrastructure.

The filter allocates memory that is never freed when the instance is destroyed" * tag 'trace-fixes-v3.16-rc5-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ring-buffer: Fix polling on trace_pipe tracing: Add TRACE_ITER_PRINTK flag check in __trace_puts/__trace_bputs tracing: Fix graph tracer with stack tracer on other archs tracing: Add ftrace_trace_stack into __trace_puts/__trace_bputs tracing: instance_rmdir() leaks ftrace_event_file->filter |
