Subject: hrtimer: remove duplicate helper function
X-Git-Tag: v2.6.26-rc2~83^2~2
X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=4346f65426cbceb64794b468e4af6f5632d58c5e;p=~andy%2Flinux

hrtimer: remove duplicate helper function

The helper function hrtimer_callback_running() is used in
kernel/hrtimer.c as well as in the updated net/can/bcm.c which now
supports hrtimers. Moving the helper function to hrtimer.h removes the
duplicate definition in the C-files.
