Subject: [tree] ftrace, v16
while all ftrace patches are submitted to lkml i thought it might not
hurt to post the full ftrace tree to lkml as well, for those who'd like
to follow its general evolution.
The latest ftrace git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git auto-ftrace-next
there is a further topical splitup as well within the -tip tree, with
these topic branches:
tip/tracing/ftrace
tip/tracing/sched_markers
tip/tracing/mmiotrace
tip/tracing/sysprof
auto-ftrace-next is their integration. These are all the bits that are
in linux-next as well.
the shortlog and diffstat can be found below. I'll send the full patch
as well in the next mail - hopefully the 300K mail gets through vger
:-)
