Subject:  [PATCH tip 0/2] utrace-ftrace engine v3
Date:  Sun, 5 Apr 2009 10:17:52 -0400

This version of the utrace-ftrace engine represents bringing v2 (as
posted along with utrace two weeks ago) up to parity with the
tip/tracing/syscalls one in terms of using the system call
pretty-printing tables.  This patch applies to the
tip/tracing/syscalls tree, except that it assumes that utrace patches
are also applied beforehand.

Next up could be adding an option to use the filterable TRACE_EVENT
tracepoint engine instead of (or in addition to?)  the hand-written
trace record management & formatting.

Next up could also be removal of the syscall-tracing prototype, if
people are so inclined.


Frank Ch. Eigler (2):
  make arch_init_ftrace_syscalls multiply callable
  utrace-based ftrace "process" engine, v3
