from Oliver Hartkopp 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. Signed-off-by: Oliver Hartkopp Cc: Thomas Gleixner --- Hello Thomas, as discussed on the OSADL workshop here is the removal of my duplicate definition of your helper function in net/can/bcm.c . The patch applies fine on Linus' current tree for the 2.6.26 merge. Thanks & best regards, Oliver
