Subject: Re: linux-next: Tree for Nov 8 (timer conversions)

timer_setup() conversion[1] status update:

As of this -next tree, there are (at least) 249 "non trivial" conversions
staged (with a matching subject of ": Convert timers to use timer_setup"),
producing:
 736 files changed, 3446 insertions(+), 4001 deletions(-)

There are 20 outstanding non-trivial conversions (all are now in-flight).
Combined with the trivial treewide conversions and API adjustments
it produces an additional:
 392 files changed, 1388 insertions(+), 1925 deletions(-)

After that, all 1116 timer_setup() callsites will be finished. My
tree, based on next-20171108, is here:
https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git/log/?h=kspp/timer/next/20171108/conversions

window. :)
