Al, I know that you do not like the releasing of the parent i_mutex lock. But it is no different than what we do today, except that we move the release out of the tracing code and into the tracefs code. This still gives us the separate tracefs filesystem that will let users mount it without needing to mount debugfs, so I want to get this into 3.20. These are the patches that I plan on submitting, and will soon be adding to my linux-next branch, to be included in linux-next. -- Steve git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git ftrace/tracefs Head SHA1: eae473581cf93dad94ca833aa961c033c6a43924 Steven Rostedt (Red Hat) (7): tracing: Only create tracer options files if directory exists tracing: Create cmdline tracer options on tracing fs init tracefs: Add new tracefs file system tracing: Convert the tracing facility over to use tracefs tracing: Automatically mount tracefs on debugfs/tracing tracefs: Add directory /sys/kernel/tracing tracing: Have mkdir and rmdir be part of tracefs ---- fs/Makefile | 1 + fs/tracefs/Makefile | 4 + fs/tracefs/inode.c | 650 +++++++++++++++++++++++++++++++++++ include/linux/tracefs.h | 45 +++ include/uapi/linux/magic.h | 2 + kernel/trace/ftrace.c | 22 +- kernel/trace/trace.c | 187 +++++----- kernel/trace/trace.h | 2 +- kernel/trace/trace_events.c | 32 +- kernel/trace/trace_functions_graph.c | 7 +- kernel/trace/trace_kprobe.c | 10 +- kernel/trace/trace_probe.h | 2 +- kernel/trace/trace_stat.c | 10 +- 13 files changed, 832 insertions(+), 142 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
