[PATCH tip 0/2] utrace-ftrace engine v3

From: Frank Ch. Eigler
Date: Sun Apr 05 2009 - 10:48:01 EST


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
